I have a Thermarest ultralight, used it in Dustin1006's Henessy, the pad and i made an x in the hammock all night long. Got my WBBB and it didn't move at all even though i toss from side to back all night.
I have one of those fleece bag liners from Wally World and a Mtn. Hardware 20 degree Pinolte bag, thought about putting me in the bag on the pad inside the fleece bag liner if it gets cold out.
Experts are the ones who think they know everything. Geniuses are the ones who know they don't.
Gather round your hearts the tinder,
lay the oak and pine together,
kindle all that is within you with a warm and cheerful spirit.
