New to sleeping bags? We have you covered. Start with what is most important to you: temperature rating, down vs synthetic, or weight.

overall best sleeping bag Sizes: Men’s, Women’s

Temperature rating (ISO): 16°F
ISO/EN are standardized rating systems that keeps ratings consistent across brands. The number is usually the lower limit rating which indicates the temperature at which a warm male sleeper still might feel comfortable.

Type: 850-fill-power goose down

Weight: 1 lb. 12 oz.

Pros: Very nice material, is lightweight for how warm it is, our best bang for the buck bag and the zipper is high quality.

Cons: The bag tapers pretty high up which makes it feel snug. Some people like the snug mummy fit and some don’t.

Bottom line: The REI Co-op Magma 15 (men’s) and Magma 15 (women’s) sleeping bags are warm and of high-quality. It’s hard to find a better cost to quality bag. REI did a really good job with this one. The mummy shape, good and hood fit well and keep you warm. The bag is high on sustainability as well as it the down is certified to the Responsible Down Standard (RDS) and contains materials that meet the bluesign® criteria (both are good things).

Accessories: If you’re looking to add a little more warmth, check out Thermolite sleeping bag liners. They can ad 5-25°F warmth to the bag and can extend the life of the bag too.

Top pick: If you’re wanting a one bag quiver for a good price this is the bag for you. Also, if you primarily camp in fair weather you may want to check out the Magma 30, which is not as warm of a bag. We recommend being choosing on the warm side… you can always take layers off.

Kelty Cosmic Down 20° ($175)

Pros: 3 season, very compressible down, DriDown creates a hydrophobic finish (stays dry longer and dries faster), lightweight for how warm it is.

Bottom line: The Kelty Cosmic 20 Degree Down Sleeping Bags are made of good down material and help keep you dry. The zipper is a well built anti-snag zipper. Great warmth-to-weight ratio.

best budget sleeping bag Sizes: Unisex

Temperature rating: 0°F
We find it keeps you plenty warm around 20°F and the 0°F rating seems like a lower limit.

Type: Synthetic

Weight: 5.2 lbs.

Pros: Best cold weather budget bag hands-down. Mummy-style bag and accommodates most people up to 6 feet 2 inches in height. The hood tightens with a drawstring to seal in heat. The quilted design helps prevent any cold spots.

Cons: The stuff sack is small and can be hard to get the bag back into it depending on how you roll up the bag. We’ve not seen any sustainability notes on this back such as meeting bluesign® criteria.

Bottom line: The Coleman 0°F Mummy Sleeping Bag for Big and Tall Adults is a great budget sleeping bag for cold weather camping. It has a good design and zipper system and is comfortable for most people. It’s not a super tapered mummy style so if you’re a bit larger you will not feel cramped.

Key Concepts

Choosing the best sleeping bag for you

Temperature rating – ISO/EN are standardized rating systems that keeps ratings consistent across brands. The number is usually the lower limit rating which indicates the temperature at which a warm male sleeper still might feel comfortable. If you are looking for a 0 degree sleeping bag or other cold weather sleeping bags, we suggest getting a bag that is rated below 0 degrees as often the rating is lower limit.

Down vs synthetic – Sleeping bag insulation primarily comes in either down or synthetic. While down insulation has a better warmth-to-weight ratio and it compacts into a smaller packed size, if it gets when you lose the much of the warmth ability and it is usually more expensive. Usually, down sleeping bags are more durable than synthetic bags. Synthetic insulation sleeping bags are usually less expensive and do a better job at staying warm when wet but they are not a waterproof sleeping bag option. Synthetic sleeping bags are bulkier and weigh more than down bags. We like down bags more than synthetic ones.

Weight – When choosing a sleeping bag, make sure you understand the temperature of where you will be sleeping and get an appropriate temperature rated  sleeping bag first and then go for lowering the weight. Better to be warm and carry a few extra oz. than be cold.

Living in the Northeast, rain happens… but now I have the knowledge and gear to go rain or shine. Glad I found this site! Thanks.

I had a few more questions about one of the tents I was interested in. After posting on the group page I got some great input. My tent is perfect for the camping I like do to.

I get cold quickly. After learning about sleeping bags here I was able to find one that keeps me warm and isn’t to heavy to carry. Thanks for sharing your expertise guys and gals.

Camping tent considerations

Warmth – Your body creates warmth that the sleeping bag captures by trapping your body heat. Sleeping bags with more insulation trap that heat better. Make sure you don’t pick a sleeping bag that is too big or else it will be less efficient at trapping your body warmth.

Getting Wet – Your sleeping bag will be not be comfortable if it gets wet. Always try to keep your sleeping bag dry at all times. Some people even pack their sleeping bag in a dry sack to keep it from getting wet while backpacking.

Down Fill The fill power of a down bag measures the quality of the down insulation in the bag. Higher fill power down weighs less and compresses more than lower fill power down. This means the higher down fill power the warmer the sleeping bag.
