    • Soft, high-loft 550-fill-power duck down insulation provides exceptional warmth and light weight
    • Baffle construction with differential cut eliminates cold spots; inner layer is cut smaller than the outer layer to create consistent thickness of insulation
    • Polyester taffeta creates a smooth yet durable shell; polyester taffeta lining breathes for comfort and feels great against skin
    • Top baffle draft collar drapes comfortably over neck and shoulders, sealing out drafts
    • Formfitting hood has drawcords of differing widths at head and neck for easy identification and adjustment in the dark
    • Ground-level side seam keeps draft tube in place, further helping prevent cold air from seeping through the 2-way, locking zipper
    • Internal loops provide attachment for a liner (sold separately) to increase the warmth of the bag
    • Pad loops provide attachment points to keep your sleeping bag and pad together, so you needn't worry about rolling onto the cold, hard ground (straps sold separately)
    • Hang loops allow easy drying and storage
    • Kelty Cosmic Down 21°F sleeping bag comes with a stuff sack

    Kelty Cosmic Down 21 Sleeping Bagis rated4.4375out of5by16.
    Rated2out of5byfromShivered to deathWent camping in Ojai. Slept in tent with rain fly up with another person. Temp was mid 40s at night. I shivered my butt off. Was wearing long sleeve shirt and pants eventually put on a sweatshirt and got a small blanket to wrap my legs in. Finally fell asleep. Zipper also snagged a little. Which I would have been fine with had I been warm.

    Rated5out of5byfromGreat BackpackBought this on a recent trip to REI in Greensboro to get a new 0 degree bag. Used it on pack from Cade's Cove to Clingman's Dome. Was very light and compacted well. Started out hiking in 40 degree and then weather turned cold and wet. Added a small liner I had brought and slept nice and toasty at 15 degrees and windy in shelter. Love it. Think it will be great in all temps.

    Rated4out of5byfromExceeded ExpectationsI needed a warmer and lighter bag to replace my old synthetic bag and saw this on offer in the Black Friday sale so I thought I would give it a try. I used it last weekend with temps down into the 20's and was very comfortable with just shorts and T-shirt. It may not be a premium brand but the quality looks good to me, I can't comment on long term durability but there is nothing to suggest it will any worse than other brands. In short, great value and great performance, you need to spend at least double the money to get anything similar and even more to get a significantly better bag. I would give it 4.5 if I could, the only negative is the zipper snags more than my other bags.

    Rated4out of5byfromKelty did it again! Great bag!This bag kept me nice and warm in the Wallowas in September and I plan to use it often. The zipper does snag, so open and close carefully, but it fits me and keeps me comfortable.

    Rated4out of5byfromGreat bag for what I'm doing.This bag is perfect for what I do. Mine is the long size which is a little wider as well. For me this is perfect because although I'm only 5'10" the bag will fit my dog when temps are low enough to worry about. I would like a lighter bag since I'm somewhat of a lightweight freak when backpacking, but the bag was on sale for a great price when I got it. I have a very lightweight synthetic 35 degree bag for summer and put together they can make a great setup for dead of winter stuff. One thing to note... I've used this bag on the beach on a very wet/dewy night and the bag remained warm after some condensation accumulated.
