My third hang this week in the backyard. Weather dropped to the mid 20s. Just got a little cold around the fringes of my two pads, and my face was a constant challenge. I had a baclava SP? on and a hoodie and a fleece hat, but I was also constantly trying to adjust my sleeping bag over it while leaving a breathing space. Harley, my Terrier friend helped keep me warm though, as well as a hot water nalgene bottle. I think I slept well most of the night though. Harley didn't seem to mind the howl of coyotes in the distance.
