20 Best Backpacking Sleeping Bag For Women (2022 Updated)

Congratulations! You have made it to the comment section, and you are debating if you should really buy the Women’s Cosmic Down 20 sleeping bag. My quick review is that it is a great bag that is incredibly fluffy, it is warm and soft and something that you would love to crawl into after a full day of hiking.

My long review… I did a gear test with my little brother, both with Kelty sleeping bags. I was with the Women’s Cosmic Down and he with the Kelty kids Synthetic down. We tested on two different nights, the lows on the first night was mid-forties, the second was in the thirties.

We were in a two-person tent and we both had mats and pillows in our front yard, so sod and damp dewy conditions. Learned instructions for use: wear appropriate clothing, you will not regret wearing long fleece leggings, even if it is mid-forties (say no to short cotton ones; learn from my mistake).

Also, do not get the bag wet, you will definitely regret it. I was cold on the warmer night because I slept with my body touching the side of the tent allowing the dew from the tent walls to rest on the bag.

While the bag is water resistant, in that I did not feel wet at all, it will decrease the warmth of the bag considerably. The second night I learned from my error and slept the best that I have ever slept in a sleeping bag and tent since before I realized the importance of sleep.

The bag was incredibly fluffy. I love the loft of this bag, it is kind of limp straight from the sack, but it gets really voluptuous as it airs up. It was super soft and the lining was silky. There was plenty of room for me to curl up and be comfortable and not too lengthy which is wonderful.

I am 5’4” for reference. I loved that it is a woman’s sleeping bag, so created for a lady’s shape and comfort (Praise the Lord!). It is marginally lighter than synthetic bags and about the same compacted size as a kids synthetic sleeping bag, almost smaller.

While not incredibly different in size and weight from a normal cheap bag, I feel like I will be grateful for the minimal difference while backpacking. While you will not be sleeping like you sleep in a warm bed at home, it was so much better than my $30 bag… (Can that even be a comparison?) I love my new sleeping bag and hope that it will last me many years.

I purchased this sleeping bag for my son to use on Boy Scout camping trips. He has not yet been on a trip with this bag yet, so my review is prior to “field testing. ” I can say that my son has slept (indoors) in this bag for the two nights since we received it and loves it.

There were some comments in other reviews about the zipper, but to me it seems well designed – just remember the fabric of this bag is delicate. I stressed to my son that you need to take your time zipping and unzipping so you don’t catch that fabric in the zipper – true for any bag.

Before ordering this bag I did a bunch of research and this one stood out because of quality and price. In the 1970’s when I was a Scout, my parents splurged and bought me a down sleeping bag. It was a great investment, lasted for decades, always warm, able to easily stuff it into the sack instead of rolling it and tying it, and super-light which is important if you’re a kid and have to carry it with your backpack full of stuff.

This bag appears very well made and I expect it should serve my son as well (or better) as my original down bag did decades ago. I did notice that the zipper was misaligned (one side of the zipper was “higher” than the other.

This is easily solved by completely unzipping the zipper and then putting the bottom “teeth” back in aligned.

I had a 12-year-old 35 degree synthetic sleeping bag that had been pretty beaten up and the filling was no longer enough to beat back mid-30s temps, even with a liner on the inside. I bought this for a trip in the White Mountains AZ when it looked like the weather was primed for one more dip.

The temps got down into the upper 20s, and I didn’t worry about a thing. This bag was a huge upgrade for me, even if this bag is a “budget” option for down bags. I don’t regret buying this at all, and I was super comfy during the trip.

The bag packs down decently small in a compression sack, too, which made it easier to pack in my backpack. Really happy with this bag and look forward to being cozy in it again.

Great bag! Exactly what I’ve been looking for as a tall side sleeper but more importantly as someone who changes sides during the night. Upgraded from a competitor’s bag which was catered to side sleepers, but had less insulation on the ‘back’.

When I would roll in the night the bag would come with me, and would end with the less insulated side covering my backside. Looking forward to using it in much colder weather, but would also give kudos as the overlapping insulation and ability to unzip at the bottom made it comfortable on a milder night in Olympic National Park last weekend.

Only critique is that the bag which it comes with doesn’t have cinch straps. With one I had from Sea to Summit I was able to get it to a much smaller size than the standard pack bag. Would purchase one for this specific bag if it was available.

It’s a little bulky, but that’s a price I’m willing to pay for comfort and warmth. I’m 5’4, 140lbs for reference. This sleeping bag is wonderful. There is plenty of room if you’re a side sleeper like I am.

I wasn’t cold once on a backpacking trip this past weekend in southwestern PA where temps dipped down into the 30’s. My boyfriend also bought the men’s version of this sleeping bag and we’ve been able to zip them together on previous camping trips for extra warmth.

I cannot recommend this bag enough!! I would also recommend the Big Agnes Q Core sleeping pad in addition to this bag. I’ve never slept better on camping/backpacking trips.

I purchased this bag for a recent camping trip and was very pleased with it. I am a side sleeper and tend to toss and turn when sleeping outside my bed. The bag easily moved with me. I also found it very soft and comfortable and with the stuff sack was easily able to get it to fit in my duffle bag with my other stuff.

Admittedly was not in temperatures anywhere near 20, probably somewhere in the 40s instead, but I found it more than warm enough while sleeping in a t-shirt and regular pajama pants. Somenights I even opened the top part to cool down some, something it made it easy to do.

Awesome sleeping bag. Got this to replace a 10 year old 32 degree Marmot bag. Nothing against my former bag, but this felt like a total upgrade. The bag is pretty roomy which is nice since it allows for rolling around in the bag without turning the bag itself (important to keep the bottom side down since it has less insulation and a sleeping pad helps with that).

The pillow pocket is clever and makes a huge difference. Whether you use an inflatable pillow or just stuff a jacket or some other clothes in there, the pocket keeps it in place so you wake up less due to your head being on solid ground.

The vents are also a nice feature as they expand the comfort range of the bag. I used this mostly in 40-60 degree weather and was plenty warm. I spend one night in it in a heated ski hut (probably about 80 degrees) and with the vents open and the top bit folded down, I didn’t feel like I was roasting alive either.

The included stuff sack is attached which is great since you won’t lose it. It also comes with built in straps so you can really compress this thing down to it’s true minimum size. It also came with a big mesh bag for long term storage.

No complaints whatsoever.

I bought this bag last year, since it seemed that it might soon be discontinued, and I was intrigued by the description. I first used this bag last week. I was looking for a bag that could keep me warm in the low 40’s high 30’s for car camping: I already own too many sleeping bags, mostly down, for backpacking, so I am fully aware of what a bag rated for 20 degrees should be capable of.

This Nemo bag is a disaster, and it is apparently too late for me to return it. To start, it would not keep me warm with temperature in the upper 40’s. It is represented by REI to have a comfort rating of 32 degrees.

Not even close. The mummy top of the bag is very difficult to tighten at all, and thus leaks cold air. The zipper is difficult to close and open at the last 10 inches or so, I believe due to the curve in the design.

I own a synthetic Montbell bag with a comfort rating of 50 degrees that sleeps warmer than this bag. I wanted a synthetic bag for at least down to the high 30’s. There is no way that I can see that this bag should be rated 20 degrees.

The question is, when does Ingenuity become gimmickry, and when does it become just another method to generate a sale. I’ll try to return it: otherwise it goes to landfill. At this point I wouldn’t even want to give this bag to a homeless shelter.

The good – I picked this bag because I only needed a 3-season bag and I’m a big girl who wouldn’t fit in a mummy bag. The size and shape were very accommodating for me. The zipper is easy to operate.

If I leave the hood as loose as possible, I could place an inflatable pillow in it and the hood kept it in place. The bag packs up into a nice small compression sack. The bad – The compression sack could stand to be just a hair bigger, but I really like its design.

The drawstring lock doesn’t lock very well. The bag, rated to 35 degrees F, is not that warm I camped for three nights in mid March on the southeast coast of Georgia, and on Cumberland Island National Seashore.

The first night, on the mainland, It got down to under 40 degrees, but I was camping out of my car and added a thick comforter over and under the bag, and was comfortable. The second night was around 45-50 degrees.

Adding a down jacket over the bag, and a large hot-hands pad inside the bag under my shirt, I was reasonably warm. The kicker was the third night, when it only dropped down to 60 degrees. I had to put on a fleece jacket to get warm enough in the bag.

Admittedly I sleep cold, but I was certainly hoping for better.

I was looking for a three-season sleeping bag that would last me for years, and I think I have found it. I haven’t camped with it yet, but the quality is exceptional. The zipper doesn’t snag, the drawstring in the hood is easy to use, and it stuffs easily into its sack (it comes with a compression sack, which separately costs about $60 and a storage sack).

I am a side sleeper, and there is plenty of room to be comfortable in the hips and legs. The only thing that kept it from getting 5 stars is the width in the shoulder. I am 5 ft 4 in, and probably a bit smaller than average in the shoulders, and I find the fit a bit snug.

I wish there was a tiny bit room up top to move more freely. Otherwise, a fantastic purchase.

I decided to upgrade after using an REI down bag for 5 years. And WOAH has it been a game changer. I didn’t think it would make THAT big of a difference, but wow! sea to summit products are incredible and this sleeping bag is certainly no exception.

most comfy sleeping bag ever! im in heaven! I just can’t wait to sleep in my tent again. I have used this in 20-30 degree F temps and have been perfectly warm. THANK YOU SEA TO SUMMIT! most quality products ever! also the color is beautiful.

the fabric is incredibly comfy. Buy this if you want to up your camping sleep happiness by 1000000000%.

I have used this bag now for two camping seasons. It is a nice, lightweight bag and the rectangular barrel shape does leave me lots of foot room or storage room for my clothes when it is chilly. I have placed a hot Nalgene bottle in as well and been quite comfy.

Pros: -Light -Decent leg/foot space (can curl up in it comfortably on my side or stretch out on my front/back -Lots of venting options (footbox unzips, half zip on off side) -Zips together with unisex bag easily and comfortably -Compresses nicely -Good hydrophobic down (had condensation on the bag at one point, dried very quickly) -Cute little inner pocket for smaller electronics -Nice draft tubes along zippers to keep cold spots out Cons: – Neck baffle/”yoke” is a little underwhelming – More contour to the hood would be nice – Can feel a little claustrophobic around the shoulders if you are a bit “stockier” built.

I’m not a large person, but I’m not super slender either and I wish this had just a little more width in the shoulders. If you’re a cold sleeper, make SURE you have a good, higher R-Value sleeping pad to get the most performance out of it.

That being said, when my pad failed and deflated last year in -5 Celsius temps overnight, it kept me warm enough with a light liner to get a little proper sleep.

Shy of 5 stars because on warmer nights (approx 60 fahrenheit) , its a bit uncomfortable in the lower body as you won’t get that airflow you would get with an ordinary sleeping bag with zipper. My lower body does tend to run hot.

I got the woman’s so not sure if that makes a difference. More importantly, this sleeping bag has kept me warm during cold nights, and I love that I can stick my feet out and wrap the flap around me and get really snug.

Another thing I will point out is that when sitting upright, the mat comes up with you and pulls at the sleeping bag leaving your upper body bare. This is slightly awkward when reaching for something at the other end of your tent, but really not a big deal.

I do like that my sleeping bag is secured to the mat during my sleep. Its a lightweight, functional sleeping bag, that you crawl into after a hike during a cold night. Its easy to pack up in the stuff bag and take on the go.

Happy with my purchase!.

Okay, first off, the quality of down in this bag is freaking amazing. It’s so light, packable, and toasty. No issues with material quality in this bag AT ALL. Also, the built in foot vent is literally the greatest thing on the planet.

However. I used it in early and late summer, down to about 12 degrees, and was toasty warm, loved it. Felt a touch drafty, but that wasn’t such an issue at those temperatures when wearing long johns and a merino shirt.

For those nice summer night temperatures, it’s perfect. Then I took it on a multi day bikepacking trip in early October. Temps were a little chilly, but well within the temperature rating of this bag (average of 2-5 degrees at night).

and I was FREEZING. That zipperless design that seems like such a great idea doesn’t seal around your neck very well, and if you shift even an inch or two in your sleep, all the collected heat trapped by that oh-so-nice goose down just gets dumped out and you’re awoken by an influx of nature’s icy breath.

It made for a rather sleep deprived trip. I would also like to note that I’m an experienced backcountry adventurer, and I usually sleep in wool long johns and a wool top–adding more layers as necessary, but I’m usually pretty good at picking the right sleeping bag for the job.

I had to wear my usual layers, as well as a fleece, a down jacket, a buff, and insulated pants just to get a bit of sleep on this trip because of this bag. Bottom line: with the design flaw of a lack of sealing around the neck, it’s not versatile or reliable enough to truly be called a three season bag, and for the price point it’s not really worth having to use only in the early/late summer or with a liner bag (because then what’s the point of having a zipperless bag to start with).

Save your money and buy something you can actually use in the temperatures it’s rated for.

As a side-sleeper I was always annoyed by the lack of mobility inside a traditional sleeping bag, that is until now. I have had this bag for just over a month now and have used it car camping and on a week-long backpacking trip through the mountains.

The design of the Sidewinder allows for the mobility to roll from side-to-side while maintaining the proper body position within the bag. And once on my side, I had plenty of room to comfortably bend my knees and my waist without feeling confined.

Also, while in the mountains above 10,000 feet of elevation, the 20-degree F. rating kept me nice and toasty.

I returned a different brand, quality bag because the mummy shape was too confined, I didn’t sleep well and afraid I’d damage the bag. I got this bag instead, and I move around and sleep MUCH better in it!!! The bag width is easily adjustable, and I couldn’t be happier with this.

Overall, I was comfortable enough down to 34-36* but started feeling a little chill through my 2. 5R camp pad. Never felt that before w/ other (synthetic) bags, even when winter camping. I don’t have enough experience with this bag to know how happy I will be with it’s insulation.

I normally tend to sleep a little bit warm. The zippers on the Torchlight require a small amount of caution, but overall I’m very pleased that I don’t have to worry too much about snags. Happily, I didn’t really notice any drafts along the zippers.

The hood still seems meant for the back sleeper. Now I’m concerned that when I’m sleeping on my side that I’m exhaling moist air into the fabric and the down. A conventional rectangular bag works so much better for the side sleeper.

I also think if the zipper was offered for left and right sides, this would help. In time, I think someone will come up with a creative solution to this side sleepers’ dilemma. It is one of two reasons I’ve been pondering getting a quilt.

There is a little pocket on the sleeping bag. It’s a great idea but is useless for me and likely for many others. My Google Pixel 5 with rugged case is still smallish, but there’s no way it would ever fit in that pocket.

Too bad, is it would help keep it warm and protect the battery. I hate that the zipper is offered on only one side- the wrong side for me. When I use my one person BA tent, the zipper is opposite of the single tent door.

When I car camp, the zipper is opposite of how I would get out of the car. Dark color is attractive and hides dirt. Light color looks like it’s for a nursery and will show dirt. No bag is perfect. If it keeps me warm enough, isn’t pink, & I can sleep, GREAT!.

Wow – this sleeping bag is wonderful. Being able to adjust the width feels luxurious, and as someone who moves around a lot/changes sleeping positions often it is really nice to have some extra room.

Pairs perfectly with my partner’s left-zip Big Agnes bag. Almost too roomy / we keep this one zipped down when paired!! Agree with the other review – cell phone pocket is in a really weird spot (ends up underneath you).

Otherwise this bag is great.

I’ve been camping/backpacking over 40 years, so I’ve been through quite a few sleeping bags. I do the alligator “death roll” in my sleep, like to sleep with room for my legs to move, sometimes knees brought up as a mostly side sleeper too.

I also like to be warm when it’s cold out (I get cold super easily). My previous Big Agnus of 5 years left me miserable every single time. It had the same degree bag rating as this NEMO but had sleeves on the bottom to fit an air mattress and l was cold from the lack of insulation on the bottom and also hated the mummy restriction.

Therefore when I was gearing up for a Yukon River paddling trip as a Scout leader in Alaska for 2 weeks I decided to get a new bag. Manny, the REI associate in Cary NC (he was from Alaska even) suggested this NEMO Disco in tall size for my sleep patterns.

He made such a great choice, big shout out to Manny! Didn’t get a chance to do a breakout so the first use was my Alaska trip. Impressions after 2 weeks: loved the material, huge cozy loft, vents, true warmth, room to move, pocket to throw my fleece in as a pillow, ability to move and roll in it and especially the flap that can flip up around my chin or cover my face.

This bag exceeded my expectations! It felt like it was made for me. The weight is light, it compressed down pretty small in my waterproof Sea to Summit bag, zippers were smooth and solid, and feathers actually stayed in the bag (compared to the mess my BA made ever since the first week I had it).

The only negative thing that I would say -and it’s only a very small negative, is that the lime green interior is too lightly colored for a hardcore camper. Luckily I brought a bag liner with me because the river is silty and we were completely muddy (even after using biodegradable wipes to get most of it off my body).

If I hadn’t used a liner the lime green interior would have been trashed in my situation so that is something to think about depending on your adventure. Otherwise, I love the cheery color scheme and really looked forward to my great nights of sleep each evening.

I think NEMO hit it out of the park with this bag, it’s seriously the best I have ever owned and will purchase more NEMO products in the future.

I absolutely love this bag! I’ve used it on backpacking trips as well as car camping and have been comfortable in high 30s to low 40 degree weather. On colder nights I’ve needed a bit of extra layering to sleep in besides just a baselayer but that’s to be expected.

I don’t know how this bag would do in winter camping but I’m not much of a winter camper; this definitely suffices for spring-fall in the PNW mountains. It’s not the most lightweight or space-efficient bag, but totally worth the weight and size to me to stay warm and sleep comfortably while backpacking.

The shape gives enough room to turn and move your legs around in the bag vs the typical mummy shape that feels a little claustrophobic and uncomfortable for me. The pillow pocket is fantastic, interior material is soft, and the blanket fold at the top feels so cozy and luxurious and lets you “tuck in” like a comforter around your shoulders/neck.

There’s also a small pocket to keep your phone in close to your body if you want to keep it from getting too cold, though if you have a larger phone it might not fit. I’m 5’7″ and got the long version, seems like I would’ve been cramped in the regular length.

Highly recommend this bag if you’re a side sleeper and like room to move. Feels like a very high quality bag.

I liked a lot of things about this bag. But ultimately returned it after my first campout. My biggest issue is the hood. It is seemingly intentionally oversized. For what reason, I’m not sure. I’m 6’5″ and got the long bag which in theory gives me 1″ of wiggle room.

I fit just right with really nothing to spare head to foot. When the hood is pulled tight, the hood hit me right at eye level or on the bridge of my nose which was very uncomfortable. If I were a tad shorter I may have been able to skootch farther down the bag so the top of the hood was at my forehead but I didn’t have any room to skootch.

I fought for two nights in a row to configure the hood confortably to no avail. It was in the upper teens at night and even with a liner I was not quite warm enough, but in Nemo’s defense my pad’s R rating was insufficient for those temps and I suspect that was the main culprit.

The bag’s construction seemed high quality and was quite comfortable besides my struggles with the hood. I liked the extra lateral wriggle room. And for a bag with as much lateral room as this, it compressed an impressive amount.

I liked both the stuff sack and mesh storage sack that it comes with. I was disappointed I couldn’t make it work but I think I’ll be looking for a bag with a normal sized hood since I can’t seem to find anything longer.

Really love this set -so versatile. Do multi-day trips across big changes in elevation. Last trip night temps went from 50 degrees to 18 degrees F. I slept at the perfect temp every night. I have used each piece separately and found they work well that way.

I am petite with large hips. I was always freezing around my hips in my previous bag. Not a problem with this set. I was worried about not having a short but the extra space is nice on the outer bag and I have not had a problem with the inner bag.

I am able to bunch it up at my feet without them getting cold or having a lot of dead space. Pros: 360 insulation for inner bag Plenty of room in inner bag -doesnt really feel like a mummy- plenty of room at hips Able to adjust system to be comfortable in any temp Dont have to carry extra sleep gear to accommodate changing temps.

Pillow sleeve helps keep my pillow in place Pad wrap keeps me on the pad, even on a slight hill Weight is worth it for the versatility and each separate piece is really light if the temps accommodate Outside bag can be used like a quilt with both sides unzipped Cons Inner bag is slick on a pad when used alone Not easy to “wear” sleeping bag in colder/winter weather Bags get caught in zippers easily- Really have to pay attention Inner bag zipper is too short- can be difficult to adjust foot temp Hood doesn’t have a cinch strap so opening doesn’t close down tight enough in cold weather Would be nice if pillow sleeve was a little longer.

Edge hits right in the middle of my pillow. Inner bag doesnt have a collar on it. Overall a great bag and worth the price especially when you consider you dont have to buy multiple bags for different conditions.

The bag should have zipper at bottom of foot box or long zipper to bottom so that temp can be better regulated and so you can walk around/sit in your bag with your boots out for really cold days/eves.

Also would be great if the zipper on the outer bag would go all the way around so you could remove top “quilt”.

TLDR: get it for the UL sidewinder inner bag, the outer quilt could use some work. Had a chance to spend a few nights with this system and the new Rapide insulated pad on Shasta a few weeks ago. Wasn’t cold enough to use both bags at once, but gave good insight into the pros and cons of each component.

*Inner Bag* This is basically the only way to get a Sidwinder UL at the moment. I think BA will make a lot of alpine backpackers and climbers very happy with a stand alone (and even a 0 deg version, I would also like to see a 0deg Torchlight).

I’m a convert to the center zip style bag (*Can I get a center Zip Torchlight Please???*). I always have trouble properly zipping a side zip, either having to squish my arm up my side, or reach over, which never works.

The center zip is easy to adjust with either hand without causing you to shift around in the bag. I sleep all over the place while camping, some days a stomach sleeper, others on my back, and more on my side, the shape was perfect for all positions (worn more like a quilt when on your stomach).

The 20 deg rated was pretty comfortable warmth in the low 30s with long baselayers during a strong wind storm. Overall a great piece of kit by itself. *”Quilt” outer bag* I was less impressed by the outer quilt bag.

The pad attachment cord would bunch up around the head with any tension, pulling sharply on my pad. However if the cord was loose, the “back” of the bag would slide around and bunch up with a little movement.

These effects were amplified when sleeping on any sort of slope, causing me to slide downhill as I slept. The one-sided closure made it hard to regulate heat, esp when you were already using the inner bag.

A 1/4 length zipper on the right would go a long way to remediate this. I think this part should go back to the drawing board. It should probably come back as a more standard style quilt with an elasticated foot box to slide over the pad, and a removable “X” strap to fasten it to the pad near the torso and over the shoulders.

While I really like the inner bag I’m disappointed that I spent nearly double the price of the Sidewinder SL for a quilt that I will probably not use. In hindsight, I would probably have preferred to pair my Torchlight UL 30 with a standard 20/30deg quilt or some similar combination.

Im considering selling the bags off and going with a standard 0 deg, I would probably try and return the bags for the above combination. However BA should release the inner bag as standalone, maybe with a phone pocket and anti snag zipper.

This is a great sleep system. There are a couple of cons, but the pros outweigh them all. First, as the name implies, it is a 3 bags in one system. The system consists of two bags that can be used individually, or combined for colder weather temps.

The outer bag is a bit more rectangular shaped, while the inner bag resembles more of a mummy bag shape. I tested the combined bag setup outdoors, but tried a night in the outer bag alone indoors. Both ways are super comfortable.

This is a great bag for those looking for options. It eliminates the need for multiple sleeping bags for different conditions – spring/summer/fall. The outer bag does not have stuffing on the underside, as it is designed to pair with a sleeping pad.

I used the Big Agnes Q Core pad, and it worked out very well. I tend to move around a lot as I sleep, so having the bag paired with a pad really helps out for not rolling off in the middle of the night.

The dimensions of the pad were right at the upper limit suggested, so it took a bit of finagling to get it together, but nothing more than a couple of seconds. The materials in the bag definitely have a lot of thought put into them – super comfortable and smooth.

I have not had the bag long enough to speak to the longevity of the materials, but nothing about it so far would have me believe that anything would go wrong. There are two cons – neither of which are that big a deal.

First, when using the combination bag, going to the bathroom in the middle of the night means dealing with more than one zipper – one on the inner bag, and one on the outer. Second, the sleeping pad.

If you don’t have a compatible sleeping pad, you’d have to go and buy that as well. However, the weight savings of not having the material on the underside of the sleeping bag means a smaller roll up in your pack/car and less weight if you’re carrying on your back.

Overall, this is a great idea and a great bag in general. I’ve seen plenty of 3n1 jackets over the years, but not many – if any – 3n1 sleeping bags. This is an excellent option for a beginner to camping who is confused about what kind of weather they’ll encounter, as well as an excellent option for someone experienced looking to downsize their gear closet.

I can see this replacing a couple of bags in my closet. I’m really happy with this bag, and can foresee me using it for years to come.

I never thought i would get used to a mummy bag but I did, especially when it got cold. 20 degrees out and I was roasty toasty in my ultra light western mountaineering sleeping bag. Seriously, when everyone got up and crawled out of their tents someone said he was freezing all night long, another agreed then looked at me and the other guy.

I said I was warm as could be and the other said he was ok but put another shirt on. Then he said I must have had a load a clothes on too. I said nope, just my shorts thats it. It really did hit 20 degrees around 5:30 am and I was absolutely comfortable tucked into my bag.

I was wonderfully warm. Hearing how the others were not so warm and miserable I felt really good about doing cold weather hiking with my choice of sleeping bags. It,s warm, very lite weight and stuffs down darn near to about a football size.

I bought this sleeping bag based on our long experience with our 40D WM bags. Although we normally are in hammocks (and use quilts), we have started using a tent in the late fall / early spring and on bicycle trips.

I am 5′ even and this bag is just big enough to allow me to stuff some clothes in the bottom and button up the hood easily. It has easily handled the lower 20’s and with some additional layering of clothing, I am sure it could be used in the mid-teens.

The quality is what you get with WM equipment and if you take care of it, lasts a long-long time. To top it off dealing with Moosejaw is a breeze.

Haven’t had a chance to test the temp rating yet, but initial impression is excellent. Very well built, extremely light, very lofty, very warm. I’m really glad I finally pulled the trigger on it. I’ve always wanted one of these bags.

It lives up to the reputation and is worth the price tag. Blows everything else I’ve had out of the water.

I’ve used this bag for nearly 2 years in all seasons. It performs! It’s bulky, but I have brought it with me backpacking. It’s worth the weight. It is so warm. I’ve used it down to 0 degrees on the lakeshore of Lake Superior in January.

You need to pair it with a decent pad, because the bottom is not lined with down. Compressed down doesn’t warm you anyways, so this just saves weight and bulk. I love that it has a slip for the pad, pillow and a pocket on the inside for your phone (or in my case, pepper spray).

Everything stays snug, so if you toss and turn like me, everything stays put. I wish it were smaller, I have to compress it with all of my body weight to get it into a 13L stuff sack. But like I said.

it’s worth it.

I was searching for a bag that was: light & packable, comfortable in the summer, properly fit – and this bag truly hit all of those marks for me! I was impressed with how easily I can pack and carry this synthetic bag for overnight backpacking trips and it comes with a great stow away sack when you are not using it.

The bag itself is really nice quality and while I have not used it on a colder night yet, on those warmer nights I did not overheat or wake up sweaty/damp with this bag! I am fairly short and the petit size was perfect for me and did not leave extra room which is what I was looking for.

Overall, I am very impressed with this bag and think it is excellent for those getting into backcountry trips or looking for a solid summer bag in general.

This bag was comfortable with some nice features (pillow holder, pockets, comfy) – however, it doesn’t meet the 15 degree temperature rating at all and, in my opinion, is dangerously misrepresented. The description states you can attach the sleeping pad into the sleeve to keep it secure and for “additional warmth.

” However, it turns out the bag is actually missing a full section of insulation on the back (didn’t realize this until I used it). The sleeping pad MUST be attached to retain any heat whatsoever. The sleeping pad I already owned was too big for the sleeve so I slept on top of it as normal and woke up shaking from the cold on a night in the mid/high 30s (well over the 15 degree rating of this bag).

On a subsequent (luckily warmer) night I did manage to attach the pad into the sleeve but was still cold. The only night I slept warm was when I lined the bag with multiple down coats, used sweatshirts/flannels as a blanket, and wore multiple pairs of socks.

None of the temperatures I used this bag in went below the mid-30s and the bag itself never kept me warm. If you buy this bag be aware you MUST have a sleeping pad of the right size to fit into it, probably a particularly well insulated one, and most likely a sleeping bag liner as well, which all drives the price up to a point where you might as well buy a different bag.

I appreciate the design of keeping your sleeping pad secure by attaching it to your bag, but a sleeping pad cannot be a requirement for a bag to meet its temperature rating (imagine if your sleeping pad pops in the middle of a trip).

Calling this a 15 degree rated bag is misleading and dangerous. Again, this bag itself retains virtually no heat due to missing a full section of insulation on the back. All that being said, I really appreciate Backcountry customer service working with me to return this bag given these issues even though it was used and outside of the return window!.

First of all, BA came through in a big way in making sure this bag was shipped on time for my winter backpacking trip. Thank you for that. Next, I would recommend this bag to anyone considering going backpacking in 30F.

Last year, I took my 20 degree bag on my first winter trip. Weather reports predicted 20-30F but it dropped into the mid teens. It was chilly but manageable with some strategically placed hand warmers.

So this year, as the same trip was approaching and the forecast began predicting temperatures in the single digits, I knew it was time to invest in a proper 0 degree bag. I went with the Anvil Horn in a Long (more room for stashing items you don’t want freezing overnight) and I’m very thankful I did.

With a Biofoam pad and an Air Core Ultra mattress underneath, I was comfortable throughout the night. And while I didn’t need the strategically placed hand warmers, I used them anyway because being warm is awesome.

I’ve used many sleeping bags and a couple top quilts. The problems that brought me to the Anvil Horn 45F were that I roll in my sleep and I have wide shoulders. My shoulders often result in my arms/elbows falling off the side of pads 25″ or less (and there aren’t any good backpacking pad options out there over 25″ wide).

The BA sleep systems, being attached to the pad, I thought, would keep my elbows in. The 45s more rectangular shape makes for a comfortable experience for people who roll in their sleep like me (much better then trying to get a mummy bag to roll with you).

The Anvil Horn did address those two issues nicely and I’m very satisfied with the quality of construction of this bag. I had this bag out on two weekend backpacking trips in the past month. I went pretty minimalist, with just tarp and groundsheet.

Nighttime temps ranged from 64F to 51F. I’m a warm sleeper. Above 60F, I was fine in underwear and t-shirt. ~60F-51F I needed long underwear. I prefer wearing a headcover then the integral head covers on many sleeping bags.

My only two issues, and they’re minor, with this product are (1) no draft collar, and (2) pad fitment. The collar has a real nice bungee cinch cord with a very well designed sandwich style cordlock. However, there’s no draft collar, that resulted in drafts down my back below 60F when side sleeping.

The 45F rating is probably realistic as a survival rating. By the mid-50s the lack of draft collar is the most notable limitation. If I can solve the draft collar issue, I’ll gladly use this bag down to freezing (with an added fleece liner or down blanket).

With regards to pad fitment, the stats for the Long indicate 20″-25″ wide x 78″ long pads are ok. My two 78″ long pads are not rigid enough to keep from folding up like an accordion when put in this bag.

So I bought a 25″x72″ pad and I’m very satisfied with that. (None are BA brand pads) I’m 6′-1″ and the Long fits perfect. Probably not good above 6′-3″ IMHO.

Excellent bag, don’t listen to people complaining about the temp rating. If you use a foam pad AND an insulated inflatable pad, as you should, it is fine. Also the temp rating, as I understand, is the lowest temp that the bag will keep you alive lol.

A night at zero degrees in this bag will be a tad uncomfortable. The features can’t be beat. The sleeve for the pad is perfect. I bought their foam pad and cut it down to fit into the sleeve also, saves a bit of bulk/weight.

Also it is lighter and packs down smaller than most 15-20 degree bags. Awesome bag. I have the mystic 15 as well, and a couple Of the Anvil horn series. As an avid alpinist that spends alot of time sleeping on snow at altitude, these are hands down the best bags.

Pleasantly surprised with the insulation properties of Thermal-Q. After searching high and low for a synthetic filled winter bag that would not break the budget. This was it! Easy zipper action, excellent / appropriately thick neck baffle to keep drafts from entering / heat escaping.

The mummy cut is really spot on if you are a long / lean type (I bought the regular length). I weigh 165lbs and measure 6’0″ (I happen to be 20″ wide from shoulder to shoulder). My only quip with the bag is how snug it actually is in the shoulders.

My other winter bag offers a little more space there (which I prefer. but can easily adapt to with this one). For those who are about my width in the shoulders be prepared for a snug fit (some might argue that it’s a little claustrophobic).

This bag offers outstanding value and will hold up for years to come (30D Nylon has proven itself for decades). As an FYI, it’s always best if you hang the bag in place of keeping it packed tight – Your insulation will love you for it.

It comes with a compression sac and given its size can get pretty small. If you are used to a down filled bag, be prepared to wrestle this one a little more to get it packed in. If you don’t like hanging your bag for storage, it also comes with a large enough mesh bag that you can toss your new sleeping bag in.

Very nice bag. High quality materials and zipper. Better than I expected. Only downside is this bag is terribly tight. The only reason I’m keeping it is because it is for a slim 11 year old. No way any average sized adult, male or female could possibly sleep comfortably in this.

Way too tight. I’m 5-11” 205 and cannot even zip it up around my shoulders! The 4 stars are for its quality and its ability to work for a slim child. If I were reviewing it for myself, it would get a very frustrating 1 star because it’s almost a home run.

No excuse for mountain hardwear to not make this much wider for average humans and still be a mummy bag.

I have been shopping at Altitude sport for many years, for this order, as good as usual, fast shipping and easy return. This is the first time I have tried a synthetic sleeping bag, overall, a bit disappointed.

It’s very hard to compress to the given small bag; even finally fitted it in, still too big to squeeze into the bottom compartment of my overnight backpack — Deuter Future Pro 36. I have returned it, looking for a down instead.

Other than this, it’s very well made sleep bag and reasonably light weight. In general, it’s a great choice for camping but definitely not trekking.

Too bad they ask for reviews before folks have a chance to thoroughly use the gear. The packed size is very large and bulky even when “compressed. ” I wish I would have gotten the Women’s Trestles Elite Eco 20 instead, as perhaps it would pack a bit smaller.

I wanted a synthetic bag for cooler weather, and usually it rains in the Appalachians, so down is always at some risk. This bag is very big, and may not fit well in my pack. The loft of the bag’s top layers look more promising than the flat “layers” on the bottom, which might not be much more useful than a quilt with no bottom layer.

At least the full surround might keep the drafts from sneaking in. -Wish the top and bottom were the same loft for side sleepers. (When you turn on the side, the bottom of the bag comes up along your back, and I expect that will be cooler with less loft.

) Time will tell.

Had bag for several months and been out on several warm weather trips, performed admirably. Tested it in “cold” weather last night low was maybe 36F. Was in a tent, which was on a tarp in my back yard.

No holes or water leaks, also had Therma Rest Z sleeping pad under. Clothing was thickish wool blend socks, fleece pants, a thermal long sleeve with t-shirt over, and a beanie. Started nice and warm.

Woke up with cold feet. Tucked in a bit tighter, sealed hood even more. Woke up again with lower body cold and began to feel in arms. Threw a thin wool blanket over myself and another plastic on one side fake wool on another.

Never got full warm. I’m a warm sleeper, last night I was not. Pity, the bag is extremely comfortable, packs well, and has held up great to all other adventures. But a low of maybe 36F in a 20F bag is a let down.

I have a marmot women’s Trestle 30 that I really like but is a little snug, so I was excited to try this wider version. It was plenty roomy for me to move around and roll over during the night. I used it with a sea to summit thermolite reactor sleeping bag liner and was plenty warm over nights that dipped to the mid forties.

I like the partial zip on the right side, it makes it a little easier to get in and also to keep open on warmer nights. The hood didn’t work to hold my full sized pillow, which kept falling off during the night.

Maybe it would work with a smaller camping pillow. The material was also loud when turning over in the night. Overall I’m pretty happy with the bag and I definitely appreciate how much room there was.

I work as a firefighter and during these late September fires at higher elevations, it can get pretty wicked cold. Last week I had my wife drive me up my Kelly dri-down cosmic 20 because the Klymit 20 degree bag wasn’t cutting it.

That night my tent grew wings and flew away before I got back to camp (later found in a creek) so I resorted to sleeping on the ground with a tarp, sleeping pad, and Kelty cosmic 20. Within 30 minutes there was ice forming on the outside of my sleeping bag and I knew I was in for a long night.

However, this awesome little bag kept me warm and content till about 4 in the morning when I had to go ***. I did the deed and returned to the bag where it kept me comfortable, not toasty, but not shivering to bad until 6am when I had to wake up.

It had to be in the low 20’s to high teens without a tent and this thing did it’s job great. So over other companies I would say these ratings are more accurate and robust. Very worth the money. Wish I had there 0 degree bag now!.

Great bag! The space-to-warmth ratio is great. While I haven’t been out for a full night as of this time, I did take this for a “test nap” at about 33 degrees and I was quite comfortable. The fit is great! I’m 5’11 and I had plenty of room at my feet, and enough room up top to maneuver my arms.

That said it’s a fairly tight sleeper so bear that in mind. One thing I will say (and this is not really a complaint) is that this comes with a stuff sack and not a compression bag. While I understand long-term compression is not ideal for a down bag, cinching it down for a day or two is pretty crucial if I want to fit this bag in my backpacking rig.

It fits great in the compression bag from my Kelty Rambler, bring it down to about 2/3rds its stuffed size. In all an awesome bag, especially for a Black Friday doorbuster. Can’t beat that!.

We bought these bags on a whim for a Boy Scout Family Camping Weekend here in Georgia where the overnight lows were going to be in the mid-30’s – and the bags we already owned were only rated for the 50’s.

No complaints on the warmth. I will admit that I was wearing a couple layers of thin base layer clothing, but once I jumped in that bag I was nice and cozy all night long! I’m about 5’10” tall, and I think if our store would have had the long bag in stock I would have bought it for the extra 6″ of length.

6 foot was long enough though for me to get the hoodie on and not feel cramped. I need to look again, but I still haven’t found the “device pouch” mentioned in the features. Buy this bag – you won’t be disappointed for the price – and Kelty is a great name! We have their tents, and always a great value for what you receive.

So far, I have a couple of nights in this bag at ~12,000 ft. in a proper four-season tent. Nights were probably in the single digits (F) and I was always plenty warm in just my thermals. Condensation around the face opening was significant, but I think that’s to be expected in the cold.

I generally run pretty warm, but I felt like I could go appreciably colder, especially if I threw on a few light layers. In terms of how the bag works, the main zipper has the effective anti-snag feature that I expect to see on most sleeping bags these days.

The draft collar has its own elastic cinch cords separate from the outer hood cinches. I find these do an adequate job of keeping things cozy. I was able to keep my pillow in the hood of the bag and still close my face in well.

A pocket lies on the very outer surface of the bag. If the ice that formed on the bag overnight is any telltale, this pocket will do almost nothing to keep something like a phone or water filter warm.

I’m not sure what the pocket really achieves. It’s relatively roomy inside. I’m on the smaller side, but I was able to fit a small bag of clothes, a liter or two of water, and my ski boot liners without fuss.

A great feature I wasn’t expecting was that a partial zipper on the opposite side of the main zipper allows you to keep the draft collar around your neck but have your arms out. This is great for getting up in the morning and getting some water boiling in the tent vestibule.

My reason for the 3-star review is that, after just two nights, some stitching is already letting go on the bag (mostly around the draft collar). I’d say the build quality is commensurate with the price; it’s not disintegrating and all the insulation is still in place, but I do fear for the bag’s longevity.

If it gets worse, I’ll definitely be looking into a warranty claim.

My friends took one look at this bag and dubbed it Carrot. Ah, well. This bag is so warm and cozy, I absolutely love it. I am a side sleeper and have plenty of room to move around in it without feeling restricted.

It takes up a lot of space in the pack, especially if I don’t use a compression sack- but so do all down winter bags. I appreciate it being relatively lightweight for a zero degree bag while still warm.

About that warmth: It’s a zero degree unisex bag, which really translates to like, a 10-15 degree rating for a women’s bag, and this tracks for me. As a woman who also sleeps cold, I’ve been in it in the twenties and been perfectly comfortable, or been in the low thirties and been slightly too toasty, in just my merino base layers and the bag (on a pad with >5 R value, also).

The one thing I would change if I could is the size of the internal stash pocket. While it’s nice to have, it’s not big enough for my iPhone which is one of the main things I’d rather have handy overnight (along with my headlamp, which it is big enough to fit but then you can’t really put anything else in there).

I don’t mind shoving my battery, in reach, and any other electronics down to the foot of the bag to stay warm all night- but those two items I like to keep handy and there just isn’t room. I haven’t used its double zipper feature yet- seems like they could save some weight by eliminating this altogether, really.

But overall, love my Carrot bag, and as a bonus the bright orange will help me be spotted if I’m ever in a SAR situation!.

After searching around for an affordable winter sleeping bag I settled on this thanks to its low weight and feature set comparable to much more expensive sleeping bags. After using it on a Saskatchewan winter camping trip, it has absolutely lived up to my expectations.

At around -20C I was comfortable in this with a Sea To Summit Thermolite reactor liner while I was wearing base layers plus a fleece top and bottoms. Once it was around -27 though I had to add in my +10C sleeping bag to feel comfortable.

I get cold quite easily though, so take that for what you will. My only gripe would be that it does not pack down very small and takes up a lot of room in your backpack, though that’s to be expected with 650 fill down.

My plan is to bring a compression sack on my next trip which should let me pack it smaller. The bag the sleeping bag comes with is just a simple stuff sack, not a compression sack like some sleeping bags have.

At 6’4 I found the tall size to be just barely tall enough, so this may not be the sleeping bag for people much taller than that. Overall, I would rate this sleeping bag very highly and would absolutely recommend it as a budget winter sleeping bag.

I’ve used this bag about a dozen times in temps ranging from 10-35F, both in a tent and in a hammock. In temps above 30, I wear a light base layer and wool sock liners. In temps below freezing, I’ll wear a heavy base layer with medium or expedition weight socks.

Most nights I’ll wear a wool hat or balaclava as well. I also pair this with a 6. 9 R value sleeping pad and when hammock camping I use the pad and a 40 degree under quilt. As far as warmth is concerned, the bag was great in high teens or above with the hood cinched.

I wasn’t quite as warm as I’d hoped when temps dipped lower than that, but I think the warmth level was well within what should be expected for this bag rating. The zippers work pretty well, and I liked the fact that I could use the two zippers together to vent out heat on those occasions where I got a little warm due to my heavy base layers.

The zipper does snag occasionally, but not nearly as bad as Marmot and North Face bags that I own. The baffles work great. I really feel snug when I pull the drawstring tight up at the top (which is easy to find and use), and the baffles along the zipper never folded up or away from the zipper which is an issue I’ve had with other brands.

If you ever feel a sort of draft or cold spot along the side of a sleeping bag, just make sure the baffles haven’t shifted. Collection of moisture around the opening and front of the bag wasn’t too much of an issue after multiple nights of use in a row.

It dried pretty quickly and the loft never really seemed to be affected. I am mostly a side and stomach sleeper, and definitely toss and turn a lot during the night. I never had any issues feeling constricted, but your experience could obviously be different depending on your size.

I could also bring my knees toward my chest pretty well when I wanted a little bit of extra warmth. I did feel like the bag was a bit tight below the knees, but it’s a mummy bag so is to be expected.

I don’t have any regrets with the purchase and think it’s a pretty good deal as far as warmth, weight, and cost are concerned. Just a note for the uninitiated: if you are sleeping on the ground or hammock camping in cold weather, you MUST invest in a high R value sleeping pad or good quality under quilt.

If you have a couple of shoulder season or summer pads, you can also double those up, but you really need to make sure you are protected from the ground or air under your hammock since the bottom of the bag has little/no insulating properties when you’re laying on it.

Doesn’t matter how great your bag is, if you are not protected from the cold ground/cold air, half of your body will be cold.

I am happy with my purchase. I got it in the $200 range before the inflation hit. It has kept me warm in 30 degree weather with extra room to spare with a 3. 4 R value pad. Regular is fine for me at 6′.

It is an attractive color and came with decent quality bags. I like that the zipper glows. I’ve lost some feathers, but I guess that’s to be expected. The only thing I I could probably knock a star off for is that this bag doesn’t pack down as small as the higher end bags.

I believe this is a mid level range bag and is good but not great when it comes to packability. I’ve packed it both in the sack and just stuffed and it doesn’t get super small compared to a higher end bag I’ve borrowed before.

At this price point, I’m not aware of any that do, however.
