Comfortable three-season camping.

Enjoy warm, comfortable, three-season camping with the Kelty Cosmic 21 Sleeping Bag.

Smart features like a top draft collar, a full-length zipper draft tube, and ground level seams keep the chill outside, and sleeping pad loops and liner loops keep everything positioned right where you need it. An included stuff sack lets this beast compress to make packing your backpack easier.

Great price, good bag

    This bag has an excellent price tag for what it offers. Coming in a little more than 2lbs, the bag has a decent weight to warmth ratio.. I stayed nice and toasty in it all night. I honestly feel like the shape of it is pretty good, maybe could use just the tiniest bit more room if you move a lot (like me). It packs well if you put it on the bottom of your bag with the stuff sack loose.i also was able to put my closed cell foam pad in the bag with me one night and was still comfortable, which is nice for cold nights. Overall, there are warmer lighter bags you could get, but for up to $300 less, this bag wins.


    Amazing weight to warmth ratio

    • Familiarity:I've used it once or twice and have initial impressions

    Amazingly lightweight for the warmth it provided at 12,000 feet sub 25 degree camping, although my feet were still cold, noting that I was not wearing a high quality base layer which could have contributed to the chilly toes.


    Nice sleeping bag

    • Familiarity:I've used it once or twice and have initial impressions

    I bought this sleeping bag when it was on sale from BC. It has only been on one trip with me so far in Glacier National Park, MT were it was used for several nights (Alpine). I have to say the is quite exceptional for the price. It has great pack size with a compression sack, decent weight and works great for me. Look forward to testing it out further. As of now, have not run into any issues.


    Just what I needed

    • Familiarity:I've used it several times

    I got this for spring/fall backpacking and winter car camping (with some extra blankets. One of the best things is how compressible it is, I got a small (10L) compression sack from Sea to Summit for when I'm packing it out. I'm a warm sleeper and am fine with just the bag when it gets to 20 degrees at night. I would recommend if you need a good, light, budget solution for your sleeping bag.
