Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

How to Choose Sleeping Bags for Backpacking

Do I really need a backpacking-specific bag?

Yes. These sleeping bags are lighter, pack down smaller and are more efficient at keeping you warm compared to ones for camping.

Understand sleeping-bag weight

Insulation type and bag shape affect weight the most. Always consider bags of a similar temperature rating when comparing loads.

Choose the right fit
Many sleeping bags come in regular, long and short sizes. Review the bag's size specs for the best fit.

Consider other features
Draft-blocking details, a snug-fitting hood, extra zippers and even a stash pocket can add more durability, warmth and function.

[This review was collected as part of a promotion.] Holy moly is this sleeping bag amazing!! This is lightweight to carry making transport a breeze. The zippers are durable and don’t snag when zipping up. I love the contour and that it’s specifically made for the female shape. The mummy design is meant to keep you toast and covered from the elements. I looove the zipper at the bottom to allow your feet out! Def for the intense campers!

[This review was collected as part of a promotion.] I am so excited to have received this sleeping bag! I plan on using it for our upcoming Yosemite trip. The color has two variations of green, which looks great and very eye catching. The durability of this sleeping bag is amazing and I know it will last multiple backpacking trips. The bag it comes in has two handles, making it easy to attach to my backpack using a carabiner at the top. It's super light, and I can roll it even tighter if needed, which is a huge plus for longer hikes. I was able to test it out in my living room and it has just enough space to not feel claustrophobic but keep me warm. The amount of down filling is impressive and I’m looking forward to a comfortable night's sleep after a long day of backpacking Yosemite!

[This review was collected as part of a promotion.] I received this ascent women's down sleeping bag free from seatosummit and influenster in exchange for an honest review. I can't express how excited I am to take this on my next camping trip. This sleeping bag is so light weight and comfortable! It comes with a travel bag that is easy to store the sleeping bag to travel with. I am 5"5 and weigh 220lbs and I fit perfectly with some room. Extremely comfortable and cozy. I love that it allows you to zip with another sleeping bag making it perfect for my husband and I. There are vents you can open if it gets too hot. Zippers and material feel very durable. I love the quality craftsmanship that went into making this product. They use non PFC and are RDS down certified. I am so impressed with this sleeping bag. I will be buying another one for my husband. I would 100 percent recommend this brand and product to all my friends and family.

[This review was collected as part of a promotion.] Great quality sleeping bag! The fabric is very silky and lightweight but once you hop inside it’s super warm! I love that it has lots of clips that will keep you wrapped in tight. For warmer nights you are able to unzip it and use it as a blanket! Would really come in handy for those colder nights camping or even for the drive in theatre!

This bag packs up small and I do like the foot hole function. But its much colder than described and there were multiple ripped seams during the first trip, ending in loss of down. Disappointed.

No, I do not recommend this product

[This review was collected as part of a promotion.] I received a free Ascent Women’s down sleeping bag by seatosummit in exchange for my honest review. This sleeping bag is extremely well made. The material is so soft and the weight is light as well for backpacking. This is rated to keep you warm in as low as 15 degrees Fahrenheit. The weather near me was not that cold but it is very warm and comfortable. The design is well thought out and I especially like how the head area curves in and can be tightened to keep out the cold. This sleeping bag is the regular size and is large enough for a woman that is 5’7’’. With that being said, I am 5’10 and I weigh 175lbs. Although I am past the recommended height restriction, I was still able to fit in this sleeping bag. My toes were right up against the bottom but it wasn’t uncomfortable. I assume that the long would be even more comfortable for my body type. The color is nice and reminds me of an avocado- dark green on the outside and light green on the inside. There is also a well thought out pocket on the inside for small items such as a phone or keys. For such a warm sleeping bag, I am super impressed with how small it can be folded into. This would be a fantastic addition for any serious hikers/campers who are looking to stay warm after a long day of hiking.

[This review was collected as part of a promotion.] The way I am 100% obsessed with this sleeping bag. As a camper, I need a durable good quality one, that will keep me warm but also allow me freedom to move. This has snaps at the top so you can keep your chest warm but your arms free and a zippered bottom so you can open up for your feet’s freedom but also have the ability to tuck your feet in and leave it unzipped. Used this for camping at a music festival with wind gusts up to 40mph. I was cozy all night!

[This review was collected as part of a promotion.] I am in love with this Sea to Summit sleeping bag. It’s the Ascent Women’s Down bag. The color is pretty and I like the aesthetic. It’s super portable. The bag is easy to carry. It can pack down small and is super light. I like all the zipper features. It’s cool that you can zip up but still leave your legs and arms sticking out. It’s very warm inside. The hood is nice as well. The size is perfect for me. Overall this bag is great and I would recommend.

[This review was collected as part of a promotion.] This is a super comfortable bag! Normally, I’m incredibly uncomfortable with a sleeping pad and bag, but the Ascent bag was so cozy! Kept me warm through the night, and the zip downs on the side were great for preventing overheating. It’s a bag that feels nice to slip into after a long day of hiking, and at around one pound, didn’t add to much to my pack. I’m excited to keep using this for the season.
