Whether you’re planning an epic mountain adventure, a multiday backpacking trip or a chilled-out camping holiday, the sleeping bag you take with you is key for getting a warm and comfortable night’s sleep in the great outdoors.
Sleeping bags come in all kinds of designs, shapes and sizes, but increasingly, brands are offering female-specific versions of their sleeping bags, made with women’s bodies in mind. Women tend to sleep colder than men, and will usually find a shorter and more curved sleeping bag fits them better, and avoids a sleeping bag taking up unnecessary space and weight. Other adaptations include more space allowance around the hip area, less room at the shoulder, and extra fill to avoid cold spots. All of this is explained in more detail in our guides on how to choose a sleeping bag and the varying types of sleeping bag.
In our search for the best women’s sleeping bags, we have tested a wide variety of styles with a broad spectrum of price tags, including both synthetic and down-filled bags designed for use in all sorts of conditions and climates.
Because, in reality, the best women’s sleeping bag really depends on what sort of adventure the woman using it is engaged in. For serious alpine use you need a bag that packs a major warmth-for-weight punch, which usually comes at a cost, whereas if you’re more of a fair weather camper who spends the occasional summer night out under the stars and attends a few festivals, then comfort and a lower price point might be more of a priority.
If you're looking for a unisex sleeping bag, check our our buying guides for the best sleeping bags and best 2-season sleeping bags, and don't forget to insulate your underside with one of the best sleeping pads.
How we tested these sleeping bags
All of the sleeping bags featured in this review were put to the test by reviewers on either side of the Atlantic - one in the UK and one in Vermont, USA. Our reviewers slept in the bags in conditions within the temperature rating ranges specified by the manufacturer and were tasked with gauging the bag's performance in a number of metrics, including warmth, comfort, weight, packed size, and materials.
The best women's sleeping bags for summer
Sea to Summit Flame Ultralight Women’s Sleeping Bag 48°F / 9°C
An extra comfortable sleeping bag for summer sleepouts and camping adventures
RRP: $319 (US) / £300 (UK) | Style: Mummy | Weight: Regular: 350g / 12.3oz; Long: 395g / 13.9oz | Max user height: Regular: 170cm / 5ft 7in; Long: 183cm / 6ft | Packsize: 2.5L to 1L | Fill: RDS-certified Ultra-Dry Down 850+ Loft | Comfort: 9°C / 48°F | Compatibility: Summer camping adventures at low altitude
The lightest, most compressible, easiest to pack, and delicious to sleep in summer bag has a women’s specific cut that’s narrower at the shoulders and wider at the hips and knees. It’s stuffed with more down than the men’s equivalent bag, and the warmth is body-mapped to give women warmth where they need it. It’s shorter than the men’s bag, but is also available in a long version. The bag packs into Sea to Summit’s XXXS sil-nylon compression sack, which is as featherweight as the bag and about half the size of a liter Nalgene bottle. A third-length zipper provides access. For adventures in colder climes, the Flame Ultralight is also available in versions that will keep you comfortable at 2°C/35°F, -4°C /25°F, and -10°C/15°F. This was our favorite summer bag, but we also used it as a liner inside another bag for fall and winter camping (find more on this in how to go camping in winter).
Mountain Equipment Women’s 250 Helium sleeping bag
A good lightweight option for warm weather camping trips where space and weight are at a premium
RRP: £220 (UK) | Style: Mummy | Weight: 680g / 24oz | Length: Regular: 180cm/71in; Long: 195cm/77in | Max user height: Regular: 170cm/67in; Long: 185cm/73in | Packsize: Regular: 22 x 18 x 15cm/9 x 7 x 6in; Long: 23 x 18 x 15cm/9 x 7 x 6in | Fill: Down Codex–approved duck down with a minimum fill power of 700 | Comfort: 8°C/46°F | Limit: 3°C/37°F | Compatibility: Summer camping and travel to warmer climes
If small and lightweight is top of your sleeping bag shopping list for a warm-weather bag, Mountain Equipment’s Helium may tick all your boxes. Weighing as little as a large bottle of water, and packing down to a size similar to one, this compact sleeping bag still packs a punch come bedtime, with duck down insulation to keep you warm in most conditions from late spring to early autumn. A snug hood stays put all night and cinches in tight. We like the Helium for warm weather wild camps and for international backpacking and camping. Mountain Equipment don’t actually explain how the female version of the Helium 250 is different, but on test we reckon nods to women’s bodies include a shorter length and smaller pack size, and extra insulation around the torso and feet.
Berghaus Women’s Transition sleeping bag
A cheap and cheerful fair-weather bag suitable for petite women
RRP: £65 (UK) | Style: Mummy | Weight: 1,380kg / | Length: 200cm / 79in | Max user height: 171cm / 5ft 7in | Fill: Synthetic | Comfort: 5°C / 41°F | Limit: 0°C / 32°F | Compatibility: Festivals and casual summer camping in fair weather
We were intrigued to see Berghaus offer a women’s specific sleeping bag for such a budget price, and wondered whether it would stand up on test against bags four times its price? The answer is that, as Berghaus attest, this is an ‘ideal fair-weather bag’. With a comfort rating of 5°C / 41°F, it’ll only keep you warm in very late spring, throughout summer and early autumn when the elements are feeling kind and you’re close to sea level. But, if you fancy going for a female-specific fit for your next summer camping holiday or festival, it’s a decent choice. The design is definitely better fitted to the female form than a unisex bag at a similar price – it’s wider around the hips, and shorter in general. The downside is that the Transition is short and small. It definitely doesn’t fit tall or curvy women well, and we’d only recommend it for teens or adults who are average height and with a slim build. There are some nice extra design touches here for the money, though, including an internal bungee cord for adjusting the hood once you’re inside the bag, and a section for popping your camping pillow in to keep it in place.
The best 2-season sleeping bags for women
Mammut Relax Fiber Bag -2C
A fairly technical but whimsical sleeping bag that performs well in a range of situations
RRP: $200 (US) / £170 (UK) | Style: Mummy | Weight: 720g / 1lb 9oz | Length: 205cm / 80.7in | Max user height: 172cm/68in | Packsize: 27 x 22.5cm / 10.6 x 8.86in | Fill: Mammut’s synthetic Ajungilak 100% Polyester insulation | Comfort: 3°C / 37°F | Limit: -2°C / 28°F | Compatibility: 2 to 3-season jaunts into non-challenging terrain
Made for warm summer nights, boondocking in a camper van, and chilling by the campfire, Mammut’s fun and funky, comfort-focused Relaxed Fiber Bag is a synthetic bag for casual outings. The bag’s fit is comfort-focused. A central zipper makes it easy to get in and out of and allows for on-the-fly temperature regulation. The synthetic hydrophobic lining and filling won’t absorb moisture, and the iridescent outer fabric and t-shirt soft shoulder and neck lining aren’t crinkly and loud. Mammut designed a new anatomical footbox into this bag to give sleepers more space without extra weight. They also added a modest draft tube to keep the cold out. The 100% polyester bag is Bluesign approved, with a PVC-free durable water repellent. It’s also Fair Wear certified. Mammut strives to ensure fair and safe working conditions in all factories making its products. It’s not the bag for scaling Everest, but it is the bag to keep in the back of the car for anytime adventures.
The best 3-season sleeping bags for women
Rab Women’s Ascent 500 down sleeping bag
Go from ‘bothy to bivvy’ with this three-season women’s bag, which boasts a water-resistant down filling
RRP: $275 (US) / £240 (UK) | Style: Mummy | Weight: 1025g / 36.1oz | Length: 200cm / 78.74in | Max user height: 170cm/66.9in | Packsize: 22 x 39cm / 8.66 x 15.35in | Fill: 650 Fill Power R.D.S. Certified European Duck Down | Comfort: 0°C / 32°F | Limit: -6°C / 21°F | Compatibility: 3-season camping adventures in campsites and wilder spots alike
Rab’s down sleeping bags are perennially popular with climbers and mountain hikers, and the Ascent 500 is a good midweight women’s-specific bag to choose from their line-up, designed to be slightly wider at the hip to better accommodate female campers. Many down-filled sleeping bags lose insulation over time, or are rendered useless if they get wet or even damp – not so the Ascent, which uses hydrophobic down treated with Nikwax, and works well even on damp mornings or inside a bivvy bag. While the bag itself is soft and comfy to sleep in, its outer nylon material is tough enough to take scrapes and scratches. Other nice little details show the quality of make and design involved, including a glow in the dark zip pull and internal stash pockets. Rab reckon the Ascent goes from ‘bothy to bivvy’ – we’d say they’re right, as long as you’re adventuring outside of the coldest weather of the year. All in all, this is a great three-season bag designed to last for many adventures to come, and light enough for camping off the beaten track.
Kelty Women’s Tru Comfort 20°F sleeping bag
A warm but weighty three-season bag that’s big on comfort – ideal for traditional camping
RRP: $120 (US) / £110 (UK) | Style: Oversized mummy | Weight: 2.33kg / 5 lb 2oz | Max user height: 173cm / 5ft 8in | Packsize: 33 x 47cm / 13 x 19in | Fill: Synthetic ThermaPro Insulation | Comfort: -3°C/27°F | Limit: -7°C / 20°F | Compatibility: : 3-season camping and backpacking
Unsurprisingly, delivering a cosy night’s sleep is the main focus of Kelty’s Tru Comfort – this women’s-specific sleeping bag is large and on the heavy side, but it’s definitely one of the most comfortable sleeping bags we tested out. We really like the oversized mummy fit, which hugs the body and keeps in heat but still allows you to wear extra layers to bed if needed, and will also suit bigger women. An innovative double layer system on the front of the bag lets you unzip different compartments for a warmer or cooler sleep – we like this feature as it makes this bag a true three-season design that’ll keep you cosy in autumn but won’t overheat on a hot summer’s night. How is the Tru Comfort female-specific? There’s an increased fill weight for added warmth, and the bag is shorter and slightly narrower in order to reduce pack weight. The only factor that may not suit some campers is the weight of the Tru Comfort – at 2.3kg it’s far heavier than many other women’s sleeping bags, and too big and bulky to work for lightweight backpacking trips. That said, Kelty’s design is ideal for car camping, campervans and traditional camping holidays.
The best warm sleeping bags for women
Nemo Women's Kayu 15°F / -9°C
A genuine 3-season performer that keeps you snug when it’s cold, but can be adapted to release excess heat in warmer conditions
RRP: $400 (US) / £400 (UK) | Style: Mummy | Weight: 1150g /2lb 8oz | Length: Regular: 185cm / 73in; Long: 198cm / 78in | Max user height: Regular: 168cm/5ft 6in; Long: 183cm / 6ft | Packsize: 32 x 20cm / 12.5 x 8in | Fill: 800FP Hydrophobic PFC-Free 100% RDS Certified Down | Comfort: -8°C / 18°F | Limit: -9°C / 15°F | Compatibility: 3-season camping in all sorts of conditions
This form-fitting ultralight down mummy bag has a tailored hood, footbox, and body-mapped core for maximum warmth without excess weight or wasted space. The 800 fill power down is sewn into ‘aggressively’ thermo-efficient patterning, according to Nemo, which prevents down migration and cold spots. The Kayu 15° features Nemo’s signature temperature-regulating Thermo Gills that unzip to partially vent the main body of the bag without creating drafts. It’s a great design feature that extends the bag's useable temperature range into warmer seasons. Waterproof breathable material in the footbox and hood plus a DWR-treated sleeping bag shell protect the Kayu from wetting out when it rubs against tent condensation. The bag is filled with hydrophobic, PFC-free, and 100% Responsible Down Standard (RDS) certified down, which is not only humanely-sourced and gentle on the planet, but highly packable, super warm, and water-repelling.
Mountain Hardwear Women’s Lamina 15°F / -9°C sleeping bag
The hardworking women’s Lamina will keep you cosy on chilly winter wild camps
RRP: $200 (US) / £170 (UK) | Style: Mummy | Weight: 1,505g / 3lb 5oz | Length: Regular: 203cm/80in; Long: 218cm/86in | Max user height: Regular: 172cm / 5ft 7.7in; Long: 185cm+/6ft+ | Packsize: 24 x 46cm / 9.5 x 18in | Fill: Thermal.Q synthetic insulation | Comfort: -9°C / 15°F | Limit: -16°C / 3°F | Compatibility: With a 3-season plus rating, this bag will keep you cosy nearly all year in most conditions
If you love camping adventures far from the beaten track but struggle to stay warm in cold conditions, Mountain Hardwear’s Lamina is our pick of the pack. The female-specific Lamina includes extra insulation in key areas such as the torso and the feet to keep you warmer, and is also one of the snuggest and most streamlined sleeping bags we tested, which along with a narrow foot box and small, adjustable hood really help to seal in warmth on chilly nights. While it’s not super lightweight, this bag is still packable enough to work in a larger rucksack for wild camping or mountain adventures, when the warmth is very welcome. The Lamina is also water-repellent and available in different lengths and zipper locations – all in all, a great choice for more adventurous female campers. If you need something for more extreme mountain temperatures, there’s a unisex version of the Lamina rated down to a whopping -26C.
Sierra Designs Women’s Get Down 20°
An environmentally considerate, versatile three-season sleeping bag for women
RRP: $180 (US) / £ (UK) | Style: Mummy | Weight: 1,120g / 2lb 8oz | Length: 188cm / 74in | Max user height: 173 cm / 5ft 8in | Packsize: 20 x 43cm / 8 x 17in | Fill: 550 fill power DriDown that is PFC-free and is certified to the Responsible Down Standard | Comfort: -5°C / 23°F | Limit: -11.67°C / 11°F | Compatibility: 3-season camping and backpacking in most conditions
Comfortable, light, and designed and manufactured to have as a low an impact on the environment as possible, Sierra Designs’ Get Down is cozy and comfortable, and also gentle on the planet. This 500-fill, three-season bag uses a water-repelling down that’s PVC-free that also meets the responsible down standard. The bag’s three-quarter length zipper is anti-snag for easy use, and it’s placed closer to the ground than in other bags so that sleepers can fold back the top for venting that feels more like your bed at home. Comes with a stuff sack. The bag has a generous but not sloppy fit, with a spacious foot box. Out tester didn’t feel like she was swimming in it, but she was able to change positions during the night without feeling cramped. Side sleepers take note, however: the lower-positioned zipper can be uncomfortable if it ends up under your hip or shoulder. And the weird hand pocket would be better replaced with a zip pocket to hold a headlamp.
Best women’s sleeping bag for side sleepers
Big Agnes Women’s Sidewinder SL 35°
A sleeping bag for those who like to curl up and sleep on their sides
RRP: Petite: $250 (US) / £ (UK); Regular: $270 (US) / £ (UK); | Style: Sidewinder Mummy | Weight: Petite: 936g / 2lb 1oz ; Regular: 992g / 2lb 3oz | Max user height: Petite: 165 cm / 5ft 5in; Regular: 178cm / 5ft 10in | Packsize: Petite: 20 x 45cm / 8 x 17.5in | Fill: 650 fill water-repellent DownTek with Bluesign-Certified PFOA and PFOS free DWR | Comfort: 1.5°C / 35°F | Limit: Not listed | Compatibility: 2- to 3-season camping at sea level or in the low hills
Designed specifically for side-sleepers, the innovative Sidewinder Series eliminates potential side sleeping pressure points while keeping women warmer and more comfortable by following feminine contours with a more gradual shoulders-to-feet taper and body-mapped insulation. Happily, our tester found the bag comfortable whether she slept on her side or stomach or back. The jacket-style hood traps warmth inside. This bag's down fill and interior and exterior shell fabric are both treated with a PFC-free water repellent finish to keep the bag from compacting from sweat and other moisture. The Sidewinder comes with a storage bag and a compression sack. And a small internal pocket holds a headlamp or a car key.
What to look for when buying the best women’s sleeping bag
Choosing a sleeping bag to help you get the best night’s sleep is an art and a science. The science is picking a bag with the proper comfort rating – get this wrong and you won’t get much sleep at all. The art is selecting a bag that ticks all the other boxes, so you look forward to sleeping out whenever you go on an adventure. To help you make the right choice, there are several important questions to ask and things to consider.
Do I need a female-specific sleeping bag?
There are few different reasons why a women’s-specific sleeping bag could suit you better than a unisex model. Women tend to sleep ‘colder’ than men and often reach lower body temperatures at night, so a warmer, more insulated sleeping bag is a sensible choice, especially if you notice that you often feel the cold when camping.
Women are also usually shorter than men – a shorter and smaller sleeping bag will keep you warmer, trapping heat around your body better, and will also be lighter and more compact to carry. Women’s sleeping bags may also be narrower at the shoulders and wider at the hips, to match the shape of the female body, or sport extra insulation around the torso and feet, where you’re likely to lose body heat.
Weight and Size
Where are you planning to sleep in your new bag? If you’re only ever going to transport your sleeping bag in a car, you won’t mind if it’s on the bulkier, heavier side. But if you’ve got to backpack around the mountains with a sleeping bag, a compact, lightweight option makes far more sense. Check both the weight and the pack size of the sleeping bag you have in mind – some of our featured bags weigh under 500g and will fit into the smallest of backpacks.
Traditional sleeping bags are rectangular, with a zip that goes around two sides. These are more spacious for sleeping, and can be opened up to serve as a quilt, but tend to be less warm and are better suited to casual summer camping, festivals and use in campervans and glamping tents. More adventure-ready modern sleeping bags are ‘mummy’ shaped – these taper around the foot and are usually lighter and warmer, and better suited to multi-day hiking and other fast and light adventures. If you are a committed side sleeper, you might want to seek out a bag that accommodates this better than standard models.
Temperature Rating and seasonality
Sleeping bags are roughly classified by season, ranging from one-season to four-season. One-season bags are made only for summer camping when the weather is very mild. Two season bags are ideal for late spring to early autumn temperatures. Three season bags are good for autumn and winter weather use, but won’t be suitable for temperatures too much under zero. And four-season sleeping bags are designed to keep you toasty on cold, frosty and even snowy winter nights, and can tackle mountain camps. As a rough rule, the more seasons a bag works for, the more expensive it’s likely to be.
Meanwhile, temperature ratings are a more specific measure of how warm a sleeping bag can keep you, and are usually split into up to three categories – you’ll see ‘comfort’, ‘limit’ and ‘extreme’ temperature ratings for most sleeping bags. Comfort is the optimum temperature at which you’ll feel warm and comfortable – meaning that if the bag is used in temperatures below that rating, you’ll probably get cold. The ‘limit’ temperature is as low as you should consider sleeping in the bag without feeling pretty uncomfortable indeed. The ‘extreme’ temperature rating refers to survival conditions – in other words, the limit at which the bag will keep you alive. In general, it’s easiest to look for a bag with a comfort rating lower than you expect to encounter on your coldest camps – especially as women tend to sleep colder than men. Find out more about sleeping bag ratings in sleeping bag temperature ranges explained.
Down is the best sleeping bag filling for warmth-to-weight ratio, heat retention and temperature range – meaning that you can use it in both warm and cold conditions. Sleeping bags made from down also tend to last longer and they’re easier to stuff into small bags. They’re also usually more expensive, however, and you’ll want to take extra care to keep your down bag dry – most down bags quickly lose their warming properties if they get wet.
Some down is treated to be hydrophobic, so in case of condensation or sweat, the down won’t get matted. So, if there’s a chance your bag will get wet, or if you’ll be primarily sleeping out in moist environments, opt for a bag made with DWR-treated down or synthetic fill (see: What is DWR?).
Synthetic bags tend to retain their thermal properties even when wet, although no one wants to sleep in a wet sleeping bag if they can avoid it. Synthetic bags typically cost less. They can also be used without fear of getting them damp, and they dry quickly if you do get them wet. They’re also easier to clean, and generally cheaper. Lastly, if you accidentally snag your synthetic bag, the insulation may be showing but it won’t leak out. This topic is treated in more depth in our explainer on Down vs synthetic insulation.
