I'm very new to Hammock camping. I slept out once in an HH Expedition, and then bought the Explorer Ultralight before a trip from Davenport Gap to Hot Springs last May. It was the last freeze in that area, and we hit it just right. One night I just froze. I'd been sleeping with my pad on the inside of my bag, and slept inside a very light liner.
In the warmer months, I could totally just pack the liner, pad, and a warm-ish top and bottom just in case, leaving the sleeping bag at home.
But was I committing a major no-no and making myself colder by having the pad inside the bag with me? I just move a lot at night, and so the pad would be EVERYWHERE if it weren't in my sleeping bag.
