I have two of these bags. I was so pleased with the first one I got the second. I've used one back packing Grayson highland state park. With only a big Agnes r-4 rated pad, thin hiking pants and thirst with a fleece jacket. It got down to 18 degrees with wind. I stayed warm. Incredible. all water supply, filtration pumps, baby wipes etc frozen solid. But this bag kept me warm. I highly recommend. Best Buy for the money.
