User Review: Kelty Men's Cosmic Down 20°
Price Paid: $70
Bought this bag to replace my bigger, heavier synthetic bag on sale this summer. I have now "test driven" it in the backyard twice, and I don't think I could have found a better bag for the money.
The first night it got down to 35 and I slept inside a tent. I had to take off my thermals and socks because I was sweating. The second night it got to 26 and I slept on a ground tarp and Therm-a-rest ProLite 4, no tent. I was very comfortable with my thermals and socks on. I think it would be comfortable down to 10 or 15 with a liner, but I haven't tried that yet. Both nights, I slept better than I ever did with my old bag.
Finally, I weighed it with my scale and it weighed exactly 2.5 pounds, just as Kelty says. I would recommend this bag to anyone looking for a good, light, small, warm sleeping bag.
