    • 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)

    Kelty Cosmic Down 21 Sleeping Bag is rated 4.4375 out of 5 by 16.
    Rated 5 out of 5 by from The most affordable down sleeping bag! This is the most bang-for-your-buck three-season sleeping bag available out on the market right now. For its price, you really can't beat the warmth, the packed size, and weight. If you can get this on sale, it would be outrageous NOT to consider this if you're looking for a bag that is: rated at 20 degrees, down (not synthetic), a little over 2.5 pounds or 1.2 kilograms, and takes up 10.5 liter volume (8" x 14" sized stuff sack). Yes, you most certainly could get a warmer bag. Yes, you could definitely get a bag that packs smaller and is lighter. Yes, you could get 800-fill sleeping bag. Yes, you could get alternative down technologies (DriDown, etc.) But is it worth 2 even 4 times the price aka hundreds of dollars more for nominal difference (mostly size and packed weight)? Out of its competition, you will see that it has similar attributes as the others: weight is a little heavier, packed size and volume is a bit smaller, temperatures are relatively the same (20F +/- 4) and all for a lower price. Great for car camping, casual camping, sleeping over, backpacking. All-around, a solid, comfortable bag for three season use. Honestly, I find this bag quite warm and mostly use it as a quilt when paired with my Therm-A-Rest NeoAir XTherm (R-value of 5.7). Because of its price, I would definitely recommend it to anyone on a budget, starting off backpacking, and is looking for a no-frills, gimmicky sleeping bag.

    Rated 5 out of 5 by from I love this bag. I have generally steered away from mummy bags as I find them too difficult to sleep in and confining. I like to go motorcycle camping and space is a premium however, so this year I decided to buy a nicer more packable bag for my trips. That meant giving up the cheap Coleman rectangle sleeping bag. I'm about 6' and 195 lbs so I tried the regular length in the store and it felt just like I remembered mummy bags, confining and clausterphobic. :( I went up to the tall size and it was fine. It was more than fine, it was a dream to sleep in. I've even pulled it out and taken naps in it in the house. It's very light, keeps my head warm, packs fairly small and has held up well so far. I would buy this again in a heartbeat. I would recommend trying the sizes out and if you're close to the max of a specific size, go up to the next one.

    Rated 5 out of 5 by from I'm in love I'm in love with this sleeping bag. I have tried many different sleeping bags over the years, wanting something for both car camping and backpacking, and this is it. On nights in the 40s and 50s, it's definitely too hot, but in that case I just lay with it unzipped and use it as a blanket. For a short woman, this sleeping bag is utterly purr-worthy. It packs down to be a very, very small bundle, it fluffs up quickly, it's pretty to look at, it's too comfortable to want to leave, the zipper hardly snags at all, and the hood is snuggly. Love this sleeping bag. I'm so happy to have finally found my baby.

    Rated 5 out of 5 by from Warm Review Used hiking - coldest temperature we saw was around 35 degrees and while the bag packs small enough in the provided bag, it could go a little smaller with a compression bag. Otherwise I was warm and comfortable without any extra clothing (slept in t-shirt and boxers).

    Rated 5 out of 5 by from GREAT product Great Price I have only used this once, during a week long car camping trip to Sequoia/Kings Canyon. WOW! I loked forward to climbing into this bag every night. Temps were in the high 20s to low 30s at night. I was a perfect temp every night...except one night I got a bit warm and had to open up the foot end to vent a little air in. Super confortable. I had enough room to roll over but the bag is not super bulky with tons of extra air space. The zipper did catch a few times on the flap, but once yout get used to the best way to lead with a few fingers it is a non issue, even in the middle of the night if you get up half asleep. Packs down super small even in the bag it comes with. If you use a compression sack it would be able to compact to an amazingly small package. Even Home Skillet the Wonder Cat approves!

    Rated 4 out of 5 by from Great 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.
