"Going Light on Cold Nights" - Review of GoLite Ultra Sleeping Bag: 20 Degree Down

I was skeptical at first on how well the Ultra 20 would last in cold weather after hearing mixed reviews. I recently bought this quilt from this site and tried it in Yosemite. It got down to freezing temperatures and I woke up with frost on my bivy sack. Surprisingly I was quite warm for the most part, but my toes were a little cold. This was due to not changing my socks before going to sleep and the perspiration around my feet rapidly cooling (my fault). I was wearing most of my warm clothing to sleep, which is what you're supposed to do with a quilt like this, and it worked quite well. The Ultra 20 is super light and when used correctly will keep you warm at night. Another great product from GoLite.
