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.

I was skeptical about the sleeping bag because of how small it is, but it keeps me really warm. I love sleeping in the cold with a warm blanket and the sleeping bag kept me nice and toasty. The zipper is really easy to zip up in the dark is good quality. It rolls up super small and fits in the saddlebag of my motorcycle.

Omg my son loves this sleeping bag! We got it for camping and he loved it so much it’s now on his bed all the time. It’s so light weight but SO warm. It’s packs down into practically nothing. Highly recommend!

Used in alaska for a vacation trip worked great!

Very surprised about how packable it is. Lightweight, packs down small, and fits great in a backpack. Plenty warm and room to move. The feet box is awesome, plenty of room for your feet. I tend to be claustrophobic in a tight bag, but this one has decent room for your shoulders.

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!

I love this bag, as it is very comfortable and warm, but... At 5'10", regular length fit me fine. But at about 215lbs, it's a tight fit. I like to sleep with my arms tucked in folded against my body, but unfortunately for me, my arms don't like it. lol. I often wake up to stretch my arms out and get the blood circulating. If this is you, I suggest going with the roomier bag. I gave it 5 stars because all in all, it's a great bag, just not the best for me. I have not stopped using it, but I may switch to the roomier bag. hope this is helpful.

Packs light and is very warm. Only thing which could be better is a compression sack.
