Reviews - The Best Women's Sleeping Bags for Backpacking

Feathered Friends Egret UL 20

  • Fill Weight: 17.3 oz
  • Insulation: Down
  • Weight: 1.4 lbs
  • Shape: Mummy
  • Volume: 09.0 L
  • Temp Rating: 20 F
  • Shell: Pertex Endurance UL
  • Fill Power: 950
  • Passive collar
  • Trapezoidal footbox
  • Generous draft tube
Feathered Friends Egret UL 20


The Feathered Friends Egret UL 20 is a high quality three season sleeping bag that is specifically designed for female backpackers. 

What we love the most about this sleeping bag is its attention to detail and female tailored fit. There is extra fill around the chest and in the foot box, two areas where women lose more heat than men. Its 950+ fill is super fluffy and toasty, making it a great option for spring to fall camping. When it comes to quality, weight, packability and warmth, the Egret beats all the other female specific bags, which is why it’s our pick for the best women’s backpacking sleeping bag. 

The biggest drawback is the price, but for this level of comfort and quality, we believe it is worth it considering it has an excellent warmth to weight ratio. Another complaint is the sizing isn’t right for everyone. The Egret comes in two sizes: 5’3” and 5’9”, if you’re somewhere right in between, say 5’6”, you might find the 5’9” option too long. This extra space traps cold air, making the bag feel colder overall. And, the 5’3” option would be too tight to have the hood fit over your head comfortably. If this might be an issue for you, you can check out the unisex version of this bag, called the Swallow which has a 20-degree and 30-degree option. 

The Egret UL is also available in a 30-degree version.

Big Agnes Side Winder SL 20

  • Fill Weight: 19.0 oz
  • Insulation: D-S Blend
  • Weight: 2.2 lbs
  • Volume: 04.3 L
  • Temp Rating: 20 F
  • Fill Power: 650
  • Body-mapped FireLine™ ECO synthetic insulation
  • Made from post-consumer recycled polyester
  • Includes storage sack and stuff sack
Big Agnes Sidewinder SL 20 Backpacking Sleeping Bag


The Big Agnes Sidewinder SL20 is spacious enough to be a game changer for side sleepers but it doesn’t trap cold air as much as other wide options.

The best thing about the Sidewinder SL20 is that it’s one of the only bags on this list that is truly built for side sleepers. The zipper and the hood face the side. The insulation and shape are all geared toward those who roll over. There is a mesh pocket for your pillow that keeps it in place. There is extra padding at the hip and feet, which are two pressure points for those who tend to flip from side-to-side several times throughout the night. There is plenty of room to curl your knees up without feeling constricted as you might in a mummy bag. 

One complaint we have with this bag is the zipper catches if you aren’t careful despite having an “anti snag zipper”. Maybe we were too rough with it but this could be annoying if you have to get up in the middle of the night. Also, people with wide feet might find the toe box a bit tight. 

The Nemo Disco 15, which is also featured on this list is a close competitor to the Big Agnes Sidewinder SL 20. The Sidewinder gains points on weight (it’s 7 ounces lighter), but it is not as roomy as the Disco. The extra inches on the shoulders and hips are nice but you also have to consider that it’s not the best design for retaining warmth.

NEMO Disco 15

  • Fill Weight: 22.0 oz
  • Insulation: Down
  • Weight: 2.7 lbs
  • Shape: Semirectangular
  • Volume: 07.2 L
  • Temp Rating: 25 F
  • Shell: Ripstop nylon
  • Fill Power: 650
  • Classic Spoon™ shape
  • Waterproof/breathable footbox
  • Integrated pillow pocket
NEMO Disco 15


The Nemo Disco 15 is a roomy backpacking sleeping bag that was designed for comfort. The Disco is our top choice for big and tall ladies who might feel claustrophobic in a typical mummy bag. It’s also another great option for side sleepers. 

What we loved the most about the Disco is its spacious dimensions. This is thanks to what Nemo calls their Classic Spoon shape, which makes the bag wider in the elbows and knees.  We also loved the Therma-gills which are vents that allow you to fine-tune the temperature without having to unzip the bag. This feature makes it a more versatile bag that could be comfortable to use in warmer temps. 

The biggest drawbacks of the Nemo Disco are it’s on the heavier, bulkier end when it comes to backpacking sleeping bags. The weight and packsize penalty come with the extra fabric needed to make this roomy bag. So, if you are a bigger girl or you just like to sprawl, and you don’t mind hauling extra weight, the Disco 15 might be the best option for you. If the weight is a big concern for you, check out the Nemo Riff 15, it’s not only lighter but also more packable. One more downside is the wider design is that cold pockets of air can form in the empty spaces, something to consider if you are a cold sleeper. 

This sleeping bag also comes in a 30 degree model. 

Kelty Cosmic 20

  • Fill Weight: 16.0 oz
  • Insulation: Down
  • Weight: 2.6 lbs
  • Shape: Mummy
  • Volume: 09.2 L
  • Temp Rating: 32 F
  • Fill Power: 550
  • Shell Material: 20-Denier Nylon Taffeta
  • Affordable
  • Anti-snag zippers
  • Moisture Resistant Durable Water Repellent
Kelty Cosmic 20 Womens Backpacking Sleeping Bag


If you’re in the market for a down sleeping bag, but can’t afford to throw down your whole paycheck, consider the Kelty Cosmic 20. This down sleeping bag has some attractive features given its low price. 

A few highlights of this bag include the durable water repellent treatment, anti-snag zippers, and a cozy hood. This gives you some peace of mind knowing your bag won’t lose insulation because of moisture or that you might accidentally tear a hole in it because of a snagged zipper. The reasonable weight is also much appreciated given the tradeoff in money typically means more pounds.

With a 550-fill-power, the Kelty Cosmic 20 won’t be the most insulated bag on the list. However, if you’re shopping on a budget, the Kelty Cosmic 20 is still an attractive option.

Nemo Riff 15

  • Fill Weight: 19.0 oz
  • Insulation: Down
  • Weight: 2.3 lbs
  • Volume: 07.2 L
  • Temp Rating: 28 F
  • Fill Power: 800
  • Unique shape offers more room at the elbows and knees
  • Waterproof/breathable foot box
  • Integrated pillow pocket
Nemo Riff 15 Womens Backpacking Sleeping Bag

The Nemo Riff 15 is a three season sleeping bag that was designed for ladies who are side sleepers who want to trim weight and bulk. 

What we love the most about this bag is it uses Nemo’s spoon shape design. It’s not a square bag nor is it a mummy bag, it’s something completely different. It is wider in the elbows and knees which gives it roomy dimensions without wasted space. The Riff uses Nemo’s Therma-gills which are vents that allow you to fine-tune the temperature without having to unzip the bag. This feature makes it a more versatile bag that could be comfortable enough to use in warmer temps. Another feature we appreciated was the pillow pocket, which you could stuff a down jacket or pillow into. 

If you’re in between the Nemo Riff and the Nemo Disco, the main difference is the Disco is made of a thicker fabric which makes it more durable but also heavier than the Riff. It also means the Riff is more compressible. So, if you’re a side sleeper looking to cut weight and bulk and don’t mind sacrificing a bit of durability, the Riff is a great option for you.

The Nemo Riff is also available in a 30 degree version.

REI Co-op Magma 15

  • Fill Weight: 15.9 oz
  • Insulation: Down
  • Weight: 1.7 lbs
  • Shape: Mummy
  • Volume: 05.2 L
  • Temp Rating: 28 F
  • Shell: Ripstop Nylon
  • Fill Power: 850
  • Generous Knee and Foot Room (for increased comfort and thermal efficiency)
  • Zipper Cover and Anti Snag Strip (for easy zipping)
  • Insulated Shoulder and Neck Yoke (which fits around your neck and shoulders to prevent heat loss)

The REI Co-op Magma 15 is an ultralight three season backpacking sleeping bag. It is a part of REI’s premium line of gear which is a great choice for hikers who want a top-tier bag without the heart attack-inducing price tag. 

The Magma 15 offers a bit more mobility for those who tend to toss and turn at night. It is spacious in the knee and foot area, meaning that you can switch positions more easily than with other, slimmer bags. Even with its wider design, this bag will still keep you toasty, even on chillier nights. 

Rated at 28 degrees F (comfort level), the goose down filling will still keep you warm. Plus, its insulated yoke (the part of the bag that fits around your neck and shoulders) is designed specifically to prevent heat loss, keeping you comfortable and warm all through the night.

Mountain Hardwear Bishop Pass 15

  • Fill Weight: 21.0 oz
  • Insulation: Down
  • Weight: 2.3 lbs
  • Volume: 08.1 L
  • Temp Rating: 26 F
  • Fill Power: 650
  • Full-length down draft tube
  • Anatomically shaped foot box
  • Stuff sack and mesh storage bag included
Mountain Hardwear Bishop Pass 15 Womens Backpacking Sleeping Bag

The Mountain Hardwear Bishop Pass 15 is a middle of the road bag that is good value while including some features you won’t find in budget sleeping bags. 

What we love about this bag is its balance between price and features. While it’s not the cheapest bag out there, it does include some clever features that make a huge difference. The draft collar lets you cinch the hood around your face which seals out the cold air. Also, the foot box has an opening that gives you some air flow if you get too toasty. Another thoughtful touch is that the pulls glow in the dark, a handy feature at three o’clock in the morning.

The biggest downside of the Bishop Pass 15 is on the heavier, bulky end of the line up. We wouldn’t recommend lugging it on long distance trips but it is manageable for short backpacking adventures. Also, it has a pretty narrow fit. If you’re a side sleeper or like to sprawl, you should probably steer clear from the Bishop Pass. 

Looking for a higher or lower temperature rated bag? The Bishop Pass line is also available in a 0-degree and 30-degree version.

Big Agnes Torchlight 20 UL

  • Fill Weight: 16.0 oz
  • Insulation: Down
  • Weight: 2.1 lbs
  • Volume: 03.5 L
  • Temp Rating: 29 F
  • Fill Power: 850
  • DownTek hydrophobic coating keeps the down warm in wetness
  • Draft tubes cover full-length zipper and Free Range Hood
  • Storage and stuff sacks included
Big Agnes Torchlight UL 20 Womens Backpacking Sleeping Bag

The Big Agnes Torchlight 20 UL is a comfortable sleeping bag with some unique design features we haven’t seen in other bags.

What we love the most about the Torchlight UL is the two expandable panels from the shoulders to the foot box which give you 10 extra inches of space. This allows you to adjust the size of the bag to fit your body shape. This way you can unzip it for more space and zip it closed to avoid any empty air space. A small but handy feature is the internal mesh stash pocket. Photographers will find it to be a great place to store batteries overnight to help keep them from draining.

The biggest drawback of this bag is the weight. Despite claiming to be an ultralight bag, it doesn’t come close to being as light and packable as other bags on our list. While the expandable design is innovative, it does add extra weight and bulk to the bag. Side sleepers might find this to be a worthy trade off.

The Big Agnes UL is also available in a 30-degree version.







Temperature rating is perhaps the most important thing to consider when purchasing one of the best women’s backpacking sleeping bags. It can get pretty cold at night in many popular backpacking destinations, and a cold night’s sleep makes for a bad night’s sleep, and a bad night’s sleep could in turn make for a bad next day!

Don’t mess around with the cold. Think about what kind of climates you will be backpacking in and make sure you choose a bag with a lower temperature rating than what you plan to be hiking in. For more on the meaning of sleeping bag temperature ratings, see REI’s super informative article, Understanding Sleeping Bag Temperature Ratings.



When it comes to quality sleeping bags, a higher price point is often an indicator of a warmer bag. However, that does not mean that you need to spend a fortune, especially if you don’t intend to camp in cold weather. For many adventurers, a cheaper bag with a higher temperature rating is sufficient. If you plan to camp in the fall, winter, or in Northern climates, though, you may want to invest in a more expensive bag that is sure to keep you warm.



As is true with any backpacking purchase you make, weight is an extremely important factor to consider when buying a sleeping bag for your next multi-day trip. You don’t want to be lugging something heavy around in your pack, especially because you’ll need a lot of other supplies, too. That being said, if you plan to take shorter backpacking trips, weight may not be as important to you. Sometimes lighter sleeping bags do not provide as much warmth as heavier ones. Check the technical specs for the bags you are considering and think about the length of treks you will be tackling when deciding how heavy or light of a bag you want to buy.



Fill is another great indicator of how warm a sleeping bag will be. Almost all of the sleeping bags on this list are filled with either goose or duck down. Both offer benefits, but they do have some key distinctions. For an in-depth look at the differences between the two, check out The Lowdown on Goose Down vs. Duck Down.





The seams that run all across the bag to help keep insulation in place.


Mummy shape

Insulated yoke

Part of the sleeping bag that wraps around the neck and shoulders to lock in warmth and prevent heat loss through the top opening of the bag.


Thermal efficiency

How well a sleeping bag locks in heat.

An insulated flap of fabric that covers the zipper and prevents cold air from entering.


Face muffler

An insulated hood that is designed to cover some of your face while locking in warmth and allowing you to breathe comfortably.


Contoured hood
