It was about 28 degrees Thursday night and I was sleeping on an insulated Big Agnes air mattress with no other pads. It was on forest floor (in a tent), no snow. I just pulled the sleeping bag over me and laid on the pad in long underwear and it was warm under me. If you move to an area of the pad that you haven't warmed, its not as warm, eh? But is was very comfy, eh? Aboot as comfy as anything that I've used except a warmlight down filled 3" air mattress, eh?
