Ladies, our team of backcountry gurus has tested 42+ of the best women's sleeping bags in the last 7 years. In this update, we purchased 15 of the latest and greatest to test side-by-side. We snuggled into these bags as we enjoyed the scenery next to glacier lakes and on the tops of 14'ers. These bags have seen all types of temperatures, conditions, and climates while sleeping under the stars and in a tent. In addition to field testing, we meticulously compare specific metrics to gather an objective comparison between all bags. Our review highlights the best sleeping bags that'll keep your pack light, your wallet full, and your body rested for many adventures to come.
The Best Sleeping Bags for Women
Best Overall Women's Sleeping Bag
Feathered Friends Egret UL 20 - Women's
Winning our Editors' Choice Award once again, the Feathered Friends Egret UL 20 continues to stand up to the stiff competition of new products on the market featuring high-quality materials in lightweight packages. The Egret still rises to the top of the game and continues to set the bar high for quality women's sleeping bags. The Egret has the highest quality, 950+ fill power down, and is super lofty while remaining among the lightest three bags we tested (all within 0.3 oz of each other!). It packs down small and has the best weight to warmth ratio of the bags we tested.
Our average height female tester who is 5'5" felt a little bit stuck in between the two sizes, for someone who's up to 5'3" or up to 5'9". She went with the larger bag, which she felt was a little too large. If you're a shorter person, you'll be excited that there's finally a bag that fits you! We love that there are three color options to choose from too. The Egret is hands down our favorite pick for any long backpacking trip, and you'll be able to stretch it from early spring to late fall with a warm sleeping pad.

Best Bang for the Buck
Sierra Designs Cloud 800 - Women's
Sierra Designs has been pushing the limits of a conventional backpacking sleeping bag and the Cloud continues to shine in this department. It's design is lightweight and innovative and its lightweight price tag blew us away. We were very surprised to discover this bag's low price tag and had to give it our Best Buy Award! The Cloud uses high quality 800 fill power down and light shell materials, combined with its clever, zipperless design, to create one of the lightest bag in this review. It is also very comfortable, using a variation of Sierra Designs' built-in quilt design, the Cloud's quilt is attached on one side so you can easily wrap it around you and tuck it in for warmth.
We did notice that the quilt can become untucked somewhat easily, making it less warm than a conventional mummy style bag. It is a better choice for summer backpacking than cooler spring and fall temperatures in the mountains, but great year-round for lower elevation, warmer climates. Comfort, weight, and packed size combine here with a modest price for what you get, making this top performer also a bargain.

Best on a Tight Budget
Kelty Cosmic 20 - Women's
Looking to break into the down sleeping bag market, but don't have hundreds of dollars to drop? Look no further than our Best on a Tight Budget Award Winner, the Women's Kelty Cosmic 20! This bag is a good quality bag that rings in at a very reasonable price. The down fill power of this bag is 600, which is similar quality to many products we tested that are much more expensive, and Kelty has improved the liner materials again, and they are even softer. The Cosmic kept us warm in temperatures down to around 30 degrees, which is about average overall, but exceptional when the price is also factored in.
Kelty has shaved a few ounces off the weight of the latest version of the Cosmic, and it is no longer the heaviest down product in this review, making it an even better value. It is a comfortable bag with a roomy mummy cut so you can wear extra layers and move around freely in it. If you're hoping to cover a lot of miles this summer and don't want to be weighed down, we'd suggest saving up for a lighter product. But if you're just getting into backpacking and want to see what it's all about, the Kelty Cosmic is a great starter bag on a budget!

Best for Comfort
Sierra Designs Backcountry Bed 700 - Women's
The Sierra Designs Backcountry Bed continues to hold our Top Pick Award for Comfort. After spending more nights in this bag camping and backpacking, it is unrivaled in the comfort department. We can't get over how awesome this bag is at making us feel like we're sleeping in a bed. When weight isn't a factor (like car camping or short backpacking destinations), we reach for the Bed every time. Its versatile quilt allows for sleeping in many positions other than in "mummy" position. When it's warm, you can untuck the quilt and have it draped or fully off of you. When it's cold, tuck it into the bag's opening, creating a cozy cradling feeling. All these things, combined with the soft liner materials, make this the most comfortable bag of the bunch.
The Backcountry Bed isn't the warmest bag overall, and you need to be conscious of keeping the quilt tucked in on cold nights. It also has a lower quality 700 fill power down than some of the higher-performing bags we tested, making it heavier and less compressible. However, if you feel claustrophobic in a traditional mummy bag and are ok with the extra ounces, the Backcountry Bed is a super comfortable choice!

Best for Best Synthetic Bag
The North Face Cat's Meow - Women's
The Cat's Meow is still the lightest and most comfortable synthetic sleeping bag we've used and wins our Top Pick Award because it is our favorite synthetic model. At a scant 2.5 pounds, it's lighter than several of the down models in this review and almost as compressible. It has an EN comfort rating of 22 degrees Fahrenheit, and we agree that it would keep us warm down to this temperature. We like that the Cat's Meow has most of its insulation placed on top where it won't compress and become useless under our body.
This bag is on the smaller side. Our 5'5 tester was barely able to get the hood over her head, so if you're taller, consider sizing up to the 'long' size. The Cat's Meow has a reasonable price tag and is the best synthetic model of the bunch.

Why You Should Trust Us
This review was crafted by outdoor educator and guide Jessica Haist. Jessica holds a Master's Degree in Adventure Education from Prescott College in Arizona. Originally from Canada, she moved to the US after growing up in Toronto, migrating to the mountains of British Columbia, and now resides in Mammoth Lakes, CA amidst her beloved Sierra Nevada. She frequently goes climbing, backpacking, mountain biking, and skiing. As an avid and multi-faceted mountain athlete who has spent time in cold environments, Jessica brings to the table a keen eye for the essential features of a women's specific sleeping bag.
There were over a hundred bags on the market that we looked at before purchasing the 15 models included here. The second component of pre-work was determining the most important things a women's bag does. We identified six key performance areas to focus on while using the bags. Then we spent a total of 5 years (spring, summer, and fall of each) taking these bags out and using them in the field. We took them on backpacking trips, like the Sierra High Route, John Muir Trail, and Mount Whitney, as well as car camping trips to the Utah desert, Yosemite Valley, and Lover's Leap near Lake Tahoe.
Analysis and Test Results
Why choose a women's specific bag? It may seem obvious, but physiologically, women are not the same as men. So when it comes to choosing something as important as a bag that will help you stay warm and get rested for a big day in the mountains, these differences should be taken seriously. Everyone wants to find the most suitable product for themselves; for most women, that will most likely mean choosing a women's specific bag. Shorter guys, if you have struggled to find a bag that doesn't have you swimming in extra material, a women's bag may be a good option for you too!
It turns out that a women's specific bag can be more bang for your buck. Almost all of the bags we tested in this review have at least the same amount of insulation, if not more, than the corresponding men's models. Women's bags are smaller and have less volume, so they end up having more fill per square inch.
After many months and seasons of testing, we compiled our assessments, crunched numbers, and wrote this review. Our lady testers' experiences with each of these bags on road trips, long-distance hikes, and summit attempts provided us with incredible insight on each bag's performance. All scores here are relative. Below we go through each testing metric and highlight which products stood out and why, and we'll also discuss the value of the different options so you can get a sense of what to look for when purchasing on a budget.
The prices of the women's specific models that we tested ranged almost across a factor of 10! Why such a big disparity, and is there a huge difference between them that warrants such a price gap? When it comes to sleeping bags, many of them use various types of down fill. The wholesale price of down varies with the "power" or loft, so a higher-loft down, say 800-fill, will cost the manufacturer more than the same amount of 600-fill. Costs, of course, get passed on to you as the consumer. Higher-loft down bags are warmer for their weight, more compressible, and typically end up scoring higher in our testing metrics. Hence our Editors' Choice Award winner, the Feathered Friends, which uses 950+ fill power down and has a hefty price tag. The Sierra Designs Cloud 800 is a little more reasonable, but still very high quality at 800 FP in that department.
If you're looking for a good value bag that still performs well but doesn't cost quite as much as the Egret, you'll have to sacrifice a little on the fill-power, compressibility, or weight, or some combination of these factors. For example, the heavier but inexpensive Kelty Cosmic, one of our Best Buy winners, costs comparatively little and does well across the metrics. Its application is more limited in comparison to our Editor's Choice winner, but it will still fulfill most needs and save you a lot of cash.
Many of the bags in this review, except the Egret, Big Agnes Hazel SL, Mountain Hardwear Lamina, and the NEMO Aya, have been EN tested for their warmth rating. The EN rating can serve as a rule of thumb for deciding which bag you should use for a particular season and makes it easier to compare between the bags that have been EN tested. Whether or not the bag was EN rated was not a huge factor in determining its actual warmth in our test. Instead, we compared these bags side-by-side in similar conditions to determine what we thought were the warmest of these bags. If you are looking for a bag to take winter camping on high altitude expeditions, consider a winter down sleeping bag. Those bags are all unisex, but many of the manufacturers make a women's version or smaller sizes.

Things to consider when evaluating the warmth of a bag are the loft and fit, along with where the insulation is located. Down bags with a higher fill power and more ounces of down fill will generally be the warmest. For instance, the Sea to Summit Flame 15 (23 ounces of fill) and the REI Magma 15 (23.5 ounces of fill) are some of the warmest of the bunch. The Egret outshines them all with its 950+ fill power and 17.4 ounces of super lofty down. This higher fill power requires less total down to create the same warmth that results in a loftier and lighter weight bag. Keep in mind that both the Sierra Designs Cloud 800 and Backcountry Bed have integrated comforters that can untuck in the night, reducing warmth.
A proper fit is essential when shopping for a bag. If your bag is too large, it can be drafty, which equals dead air space that your body will need to work to warm up. The Kelty Cosmic and the Marmot Angel Fire bags fit most of our testers very well, with enough wiggle room to wear a few extra layers when it gets below freezing, but no spare room for cold air. The fit is one of the most compelling arguments we can make to purchase a women's specific bag. We like the Cat's Meow's cozy baffles that stop air from getting in along the zipper and around the neck. The bags that included draft collars like the Flame, Magma, and the Mountain Hardwear Lamina offer a little extra element of warmth. These draft collars blocked the cold drafts from entering and retained our body heat inside the sleeping bags.
Many manufacturers are being more strategic about where they are placing their insulation — especially for women's specific bags. As women are known to sleep colder, manufacturers are putting extra insulation into their women's models, and often they put it into the foot box for ladies' icicle feet. The Rab Neutrino 400 - Women's and the REI Joule 21 both have more insulation than their unisex counterparts. The Marmot Trestles Elite Eco 20 and The North Face Cat's Meow both have extra insulation in the hood and foot box areas specifically. The Feathered Friends Egret has way more down fill than its counterpart unisex bag, and it is the warmest bag we tested. Both the Cat's Meow and the Lamina have most of their insulation on the top of the bag, where it won't be compressed underneath you, and the Eget has continuous baffles that allow you to move all the down on top of you for extra cold nights (or beneath you on warm nights).
When planning your backpacking kit, one thing to consider is choosing a sleeping pad that will add warmth, especially if your bag does not have insulation on the back. The higher the "R-Value," the more the pad will insulate you from the ground. We love our Therm-a-Rest NeoAir XLite - Women's and the super warm Therm-a-rest ProLite Plus - Women's pads.

Women are typically smaller than men. Women also have, on average, less brute strength and less lung capacity than men, so all advantages are welcome when it comes to reducing pack weight on a long overnight trek. Why would we want a heavy, bulky bag to haul around? No backpacker wants to add extra weight to her pack; we all want to have a bag that will have the greatest weight-to-warmth ratio. Of course, if you are looking for a car-camping bag, this metric shouldn't be a deciding factor for you. The weight of a bag is a sum of its fill type and power, shell materials, and features.
Over the past few years, we've noticed more and more that many manufacturers are touting their products as "Ultralight." We think this word is being overused, and none of the bags in this review are what we consider truly Ultralight. Synthetic insulation is typically denser, as is down insulation with a lower fill power, like the 600 fill duck down found in the Kelty Cosmic since you need more to achieve the same warmth. Having a lighter weight shell material will lighten up your bag — but these light materials are often much less durable than a heavier shell material. Bags with sleeping pad sleeves, like the Hazel SL, tend to be heavier, even without insulation in the back of the bag, because this material is usually heavier than insulation. The more features your bag has, such as double zippers and pockets, the heavier your bag will be - so you need to decide if you want that pad sleeve or can go without such an amenity.

The Egret, Neutrino, and Sierra Designs Cloud 800 are the lightest bags in this review, at 27.5 oz. 27.2 and 27.4 oz, respectively. This achievement is a result of their high down fill power (950/800), lightweight shell materials, and a simple list of features. The Cloud doesn't even have a zipper, which cuts weight. If you're not planning on carrying your bag around much (except in your car or a boat, for instance), consider getting something that is heavier, less expensive, and has more comfort features. If this sounds like something you're after, the Marmot Trestles Elite Eco - Women's, with its synthetic fill and two zippers for easy opening, is a good choice. Another way to lighten and tighten your load is to find yourself a lightweight compression sack as most of the included stuff sacks are heavy and bulky, although the Nemo Aya and Flame's are excellent.
When you're working hard during the day, you want to sleep well at night. The most important factors affecting comfort in these bags are the size, shape, and shell materials.
Lately, it seems like manufacturers have been going to great lengths to figure out how to make the traditional mummy design more comfortable. Through many nights evaluating bags, we have found that comfort is a direct correlation between shape and size. Often the roomier the model is, the more comfortable, like the Hazel SL or the Marmot Trestles. Unfortunately, these bags are less warm than other, tight-fitting ones.
The Sierra Designs Backcountry Bed has a genuinely innovative bed-style design and is the most comfortable model we tested. It feels like you're sleeping in a bed with a comforter, although it still has the mummy shape around the legs, which will feel restrictive to some people. The Backcountry Bed and the Cloud both also sport an innovative foot vent that you can slide your feet through, without letting in cold air. The Marmot Trestles is quite comfortable, with lots of room to move around inside the bag and two zippers that allow for your arms to come out with ease; it also has a quilted effect, much like the Sierra Designs options.
Shell and liner materials are also an essential factor for comfort. We prefer the soft, silky material of the Rab Neutrino next to our skin. Kelty has updated the Cosmic Down's shell and liner materials, so they are softer and more comfortable against the skin than previous models.
When it comes to your sleeping bag, size does matter. If you are carrying it on your back for multiple days, you want it to become as small as possible, so your pack can remain compact for good balance and maneuverability in tricky terrain.
Down fill is much more compressible than synthetic insulation, and thus the down-filled Rab Neutrino has the smallest packed size. The Nemo Aya and Cloud are also very small. The synthetic Marmot Trestles and the Mountain Hardwear Lamina are the bulkiest of the bunch. All of the products in this review come with some form of stuff sack, but most are not compression sacks, which we prefer for squeezing these into the smallest bundles possible.
Remember that compressing your down bag shortens its lifespan; this is why most manufacturers include a large cotton or mesh storage sack with your purchase. Unfortunately, Kelty does not provide one for the Cosmic. The one that comes with the Flame is on the small side, so the down is still being slightly compressed. Always store your bag uncompressed.
In this category, we evaluated shell material, zippers, pockets, baffles, drawstrings, sleeping pad sleeves, and any other added features these bags may have. We also note what features are necessary and useful in comparison to features that are superfluous and make the bags heavier and more cumbersome. We like the streamlined features of the Neutrino 400 because they are all designed with weight savings in mind. Its soft, lightweight fabric, small stow pocket, and high-quality 800 fill down with no other bells and whistles make this our favorite simple-featured bag. The Cloud 800 and Egret are also very simply featured.
Almost every down bag in this review now comes with some type of hydrophobic down, so it seems that manufacturers are on a level playing field in this department. Each company has a proprietary hydrophobic down; Mountain Hardwear has Q Shield, Rab uses Nikwax, Sierra Designs uses DriDown, and so on.
The effectiveness of hydrophobic down is a difficult thing to test, and people online have done everything from getting in the shower to jumping into frozen lakes to try and test the effectiveness of a manufacturer's treated down. Things are looking good online as to the actual performance of this treated down, but skepticism still exists as to how beneficial the treatment is. One consideration is that this coating can add around an ounce to your bag, along with the potentially harmful chemicals that may be off-gassing on you when you sleep. We asked Feathered Friends about why they don't treat their down and here's what they had to say:
"We made a conscious decision not to treat our down with a water repellent coating. Although waterproof down has recently become popular in the outdoor industry, we find that it compromises the down's effectiveness and longevity while providing little real-world benefit. We also have concerns about the widespread and excessive use of PFCs, which have a demonstrable negative impact on the environment. Because we take such pains to source high quality down and take such pride in the quality of our products, we don't have any plans to use down treatments, and, as far as I know, neither do Western Mountaineering, Arc'teryx, or other purveyors of high-quality down products. We do, however, use a DWR on all of our fabrics, which should be effective in keeping out moisture from condensation, ice, or light precipitation."
A trend we've noticed recently is burly "anti-snag" zippers and extreme measures taken for zippers not to get caught on the bags' shell material. The Angel Fire's "zipper garage" is enormous and probably weighs an ounce itself, but we will say that it never catches on anything. Feathered Friends and Mountain Hardwear also employ these zippers on their bags.
With so many women's products on the market these days, we hope we've been able to help you determine what will work for you and what is just industry hype. We've shared which ones are our favorite for carrying around and sleeping in, and hope you feel confident selecting the right one for you. Good luck and happy trails!
