Kelty Cosmic 20 Down Mummy Sleeping Bag for Backpacking, Campers, 550 Fill Power, Recycled Fabrics with PFAS-Free DWR, Designed in Sunny Colorado,

I bought the Kelty Cosmic Down 20 for fall backpacking trips and so far it has totally exceeded expectations. It kept me warm in temps down to the high 20s °F with just a base layer and a decent sleeping pad. The down insulation lofts up nicely, and I really like the hood and draft collar features—little things that make a big difference on cold nights. It packs down smaller than I expected (fits in my 50L pack with room to spare), and for the price, this is probably one of the best value down bags out there. It's not ultralight, but it's light enough for most weekend or multi-day hikes. Only downside is the mummy shape is a bit snug if you toss and turn. But the footbox has enough space and I still slept comfortably. Highly recommend for 3-season use if you want warmth and quality without breaking the bank.

Excellent bag, well built, lightweight, and warm, perfect for backpacking. Comfortable down to about freezing (32°f). I am 6' 2" tall, about 26" across at the shoulder. I purchased the long version. Length is good probably fit a guy up to 6' 6". However the bag is "snug" at the shoulder and arms. Not tight per say but not a lot of room eather. Difficult to fully zip and unzip because it is tight with one arm flexed or "bent" in order to zip. If you are a barrel chested, muscular, or husky man you are not going to like this bag. I have taken to using it as a blanket. Otherwise very happy.

Don't put in washer!!!! Very cozy and warm and perfect size! Good for backpacking and camping in cold weather.

Very warm, high quality bag! I’ve owned several sleeping bags and I got this as a spare but I wanted to try it out and was very pleasantly surprised! Not only was the stitching and zipper high quality, but it retained heat much better than I expected for how light it is. 10/10 would recommend to anyone in need of a sleeping bag!

Very warm, just wish it had a few vents in it. I'm 4'10 so trying to find something with out too much extra space is a struggle. I recently used this on a camping trip where it got to the low 30s at night on a humid mountain. I was honestly afraid I was going to be super cold but instead I sweat the entire night. I ended up unzipping the side but that left me a little too cold. If this thing had a 2 way zipper so you could just do a small portion or some vents it would have been perfect! Overall I guess id rather be too warm than too cold so can't complain too much.

Excellent sleeping bag, rolls up very small, ideal for backpacking. It’s also very fluffy

Only used once so far. Super comfy and kept me warm in 36F tent camping. Very soft and rolls up easily back into provided storage sack.

I've had this bag in very cold ❄️ weather and stayed warm,kelty is a good brand.
