Kelty Cosmic 0 Down Mummy Sleeping Bag - 550 Fill Duck Down Winter Backpacking Sleeping Bag

Great sleeping bag. Spacious enough for me to roll onto my side in the sleeping bag. Not too constrictive for a mummy bag. Temperatures got down into the 30s and I actually had to unzip the bag because I was getting too hot. Read more

Kept me warm and cozy this past winter. Only camped in weather down to high teens, low twenties, though. Ergonomics of zipper and hood are excellent. Toe box is the right size for me, 5' 7", US size 10 feet. Definitely only buy this if you're going winter camping, though. It'll be unnecessarily big and bulky to carry around in other seasons, not to mention too warm. Read more

Best sleeping bag I have ever owned. It keeps me super warm, almost too warm if its above 20 degrees. Great quality for the good price. Besides the zipper its easy to use. The sides can be tight for broad shoulders. Cons: quilting does move a little bit and you have to readjust it Feather come out of it Zipper can be difficult especially near the neck Read more

Arrived promptly and was exactly as I had hoped. Kelty makes top shelf products at half the cost of other known and trusted brands. It is extremely warm and very very comfortable. So far I haven't even zipped it up. Would absolutely buy this again. Read more

Warm enough. Some dead spots in the insulation but still stays warm. Read more

A good, solid, down sleeping bag. The design is much the same as early bags for some of the larger outdoor firms. The cut of the overall pattern is tight for an adult. However, this means it is thermally efficent. I am on the large side, being 6',4", approx 238lb. and rather wide shoulders at 48 to 50 inches. When I tried this bag in long, I felt snug, but with room to move if needed. As to the tearing and fragile sewing, well you need to take care of your gear. So far a good bag. I hope to review more at a later time after some use. Read more

Warm and cozy, love it! Read more

Very surprised this doesn't have better reviews, it's a high quality feeling product that did it's job well. I used for winter camping conditions in the mountains on an elk hunt. The temperature dipped well below freezing and this bag kept me warm. It's the only bag that's ever kept my feet warm, I like the large foot space and extra insulation there. The long length was perfect for my height 6'4". *Note - Obviously be smart when camping in cold weather conditions! If the weather drops below freezing and you didn't bring a heat source, decent tent, thermal layers, wool socks and a pad to keep you off the ground, you will be cold even with a nice bag. Read more
