I just had my first hang over the weekend and loved every minute of it! For insulation I used a 20 degree Phoenix and a 20 degree Burrow and it was great for my WBBB! Hammock Gear puts out some high quality products! Got down to 37 and I only got a little cold around 3am. So I woke up, relieved myself, and made a slight adjustment to the Phoenix and was warm as could be! My head got a little chilly as well, but since I'm a side sleeper I had plenty of top quilt to pull over my head. Nearly perfect night!
