Just ordered one of these after much waffling. This is my first season in a hammock, and I have camped in my WBBB DB 1.0 for 15 nights using an older 25 degree Sierra designs synthetic bag and a therma-rest pad (hard to stay on top of) or (more recently) a home made reflectix pad. I live in Michigan, and have slept a little cold using that set-up on some nights when the temps were around the freezing point, even when wearing long underwear and a fleece jacket. I hoping that getting this and making it into quilt will give me a lightweight, compact warmer weather options, and that I can use it in conjunction with a 40 degree bag to cover the colder weather. need t do some about bottom insulation. Reluctant abandon the pad in case I have to go to ground, but I dislike the bulk and if I get cold, it always seems to be from the bottom.
