The Kelty Cosmic 20 Degree sleeping bag is ideal for 3-season backpacking and camping. Lightweight, hydrophobic DriDown fill and an array of features make the affordable sleeping bag a real bargain.
The Cosmic 20 Degree sleeping bag is insulated with 600-fill power DriDown. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel, and despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the DriDown featured in the Cosmic 20 Degree bag performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry longer and dries faster, should it become wet, than that in bags with untreated down.
Baffled construction eliminates cold spots, keeping outside air from reaching the interior of the bag. A draft tube behind the 60" two-way locking zipper, a fully-insulated draft collar, and a contoured hood with an insulated hood baffle further enhance the thermal efficiency of the Cosmic 20 Degree bag. The hood utilizes Kelty's patented FatMan and Ribbon drawcords, allowing you to adjust the top or lower sections of the hood by feel even when it's dark outside. A polyester taffeta liner provides internal comfort.
The Kelty Cosmic 20 Degree sleeping bag is available in Short (fits up to 5’ 6”), Regular (up to 6' 0"), and Long (up to 6' 6") lengths. Each Cosmic 20 Degree bag includes a stuff sack.

Real Customer Reviews
- Nice budget down sleeping bag
Likes: It's not expensive for a down bag. Like the color. The zip is two way design. It's lightweight.
Dislikes: I got another down sleeping bag from Marmot and it comes with a big storage bag and a stuffed bag. However, this one only comes with stuffed bag and does not have storage bag so that I have to get a storage bag for it.
- This bag is so nice I bought it twice!
Likes: I bought this for my son a few years ago and it was such a good bag I bought one for myself. Very comfortable, lightweight, perfect backpacking bag for cool Rocky Mt. nights.
Dislikes: I do not have any problems with this bag, I would recommend it.
- Great Bag for the money.
Likes: Cheap price
Slept cool on warm evening.
Dislikes: None yet, but I’ve not used it on cool evening yet.
- Tested in 30 degree temps
Likes: The bag was great in recent 30 degree temps. I slept with boxers and a tee comfortably. My girlfriend has the women's version and was also very warm in our first test. I was previously using a cheap $30 bag from amazon purely because of its size. This bag is virtually the same size and weight, but light-years more comfortable and warm. I really enjoy the size of the hood and the extra room inside the bag. I was able to sleep on my back, then roll to my side without needing to adjust the bag around me while moving. I'm 6ft tall and I got the long version. I think I could have gotten by with a regular as my feet have plenty of room in the end. I would recommend this bag 100%.
Dislikes: The hood is a bit difficult to tighten down and loosen as the tensioner is on the outside of the bag and your hands are inside. I may honestly be doing it incorrectly though.
- Great sleeping bag
Likes: Took it to a three-day backpacking trip last weekend. Gave me comfort in low 40 F rainy nights. Like the hood as well.
Dislikes: Not fit enough to trap the body heat.
- Great Sleeping bag
Likes: - very soft
Dislikes: -somewhat snug but that is expected
- Nice bag for the money
Likes: Packs down small. Fairly light for the price. Looks to be well constructed. Haven’t got to try it out yet
- Down performance without breaking the bank.
Likes: Lightweight, very packable (for a 20 degree bag), very warm, soft interior. It is a great down bag for a great price! Kelty is a tried and true company and this bag is perfect for a 3 season bag.
Dislikes: None so far!
- A great bag for a nice price!
Likes: Packs small and feels light. I used it for a 3-day trip with weather in the 30's and it kept me warm enough. The ability to close the hood kept in body heat nicely!
Dislikes: I noticed that it had an unpleasant smell after first opening it, but after airing out the bag, the smell seems to have gone away.
- Great sleeping bag!
Likes: It is very light but warm. I slept with my face open to the air, and my face was the only part that got chilled.
Dislikes: There were nothing I disliked from my first use.
