It's light, it's warm, and it's comfortable. I slept out for a couple of nights in this bag to test it out. The system used: a small tarp to keep precipitation off of the face, a sleeping pad, and an old military bivy bag. The first night was in the thirties (F) I believe. The bag was soooo hot that I had to unzip it from the bottom to stick my feet out and had to have my head outside. This was in less than a base layer. It felt like it was 100 degrees! Everyone said it had been 30 degrees, so I must believe them. The next night the temperature was around the 9-12 degree F with the windchill at 3 degrees F. I was warm in just a base layer. I slept comfortably through the night and did not even notice that an inch and a half of snow had fallen on my bivy sack that night.
