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.

Great value down bag
Reviewed by Shannon F. - August 18, 2018

Likes: Down bag on a budget? You can't beat this deal. Of course, I would love a 1 lb minimalist 800 fil down quilt but who wants to spend $400+. With comfy merino wool base layer pj's and an insulated pad, this will do the trick for a fraction of the cost. Very comfy.

Dislikes: Grab yourself a compression sack. You can definitely get this smaller. and you can grab a mesh bag for storage at Big 5 for 7 bucks.

Roomy and Well Constructed
Reviewed by Rick B. - August 13, 2018

Likes: I am 5' 11" tall and weigh 180 lbs. The KELTY COSMIC 20 DEGREE SLEEPING BAG has plenty of room for me. The outer shell is a heavier weight fabric than my other 25 degree bag, but according to specs it's only 3 oz. heavier overall. The construction and workmanship is very good. I agree that the bag is a good value.

Dislikes: None.

Great Budget Down Bag
Reviewed by Mark H. - August 9, 2018

Likes: The extra room is great. I can actually put a sleeping pad inside the bag adding to the warmth. Much roomier than most mummy bags. I use a klymit static v and I weigh 200 and can zip it up no problem.

Dislikes: The zipper works but is a challenge. It gets caught and will need to practice it. May be too roomy for smaller guys.

Not sure how I could have done better.
Reviewed by Brian K. - August 3, 2018

Likes: Warm. Quality construction. Looks great. I bought the large and glad I did since I can roll my body inside when zipped for side sleeping. I'm 5'-10" and think the medium would have been too small for my liking. Stuffs nicely in included sack into size not much larger than my companions strapped compression bagging of a more expensive bag. Used in a recent 3-day hike in Rocky Mountain National Park and it was perfect for the nights at 10k to 11k feet elevation in late July early August.

Dislikes: None.

Great bag, a little slim around legs
Reviewed by Brandon L. - August 1, 2018

Likes: Plenty warm and comfortable

Dislikes: Slim fit throughout for a fairly slim guy-wish there was a wide option offered.

Great budget down bag
Reviewed by Jacob V. - August 1, 2018

Likes: Roomy, light, packs small, feels durable.

Dislikes: None so far.

Incredible at the price range
Reviewed by James W. - July 22, 2018

Likes: Incredible and everything I needed to brave the snow storm.

Dislikes: None

Very impressed with this bag so far. Have taken it on a few trips and very happy with how well it has done keeping me warm. Very nice down bag at a great price!

Dislikes: Wish it had better foot bed ventilation

Nice budget down sleeping bag
Reviewed by Summer - June 22, 2018

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!
Reviewed by Bill J. - June 18, 2018

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.
