Hey whats up... Just thought id chime in...Ive been sleeping in my hammock (hennessey) for a few years worth of multiple week hikes and weekenders without adding too much extra weight for cold nights...really all you need is an underpad, a cheap $6 one from wally world has served me well and kept me plenty warm.. Even when it gets down to 17*f. It does take away ever-so-slightly the "hammock" comfort..Its not even really noticeable.And hey It still beats sleeping on the ground lol!!!! But heavy rain, wind, i havent had a problem at all... I use the Hennessey HEX Tarp with plenty of room to spare to cook or shade... if ya can get a cat-cut id do that tho... actually just got back from the Sierra-Nevadas a few days ago, 8 nights in the hammock on the edge of a 40-50ft cliff overlooking a beautiful lake... Still 10-15ft of snow on most of the trails where we were and still ended up sleeping with the tarp in the SnakeSkins <----- GET Snake Skins.... they are great.... check out (*and mod edit this if im ont allowed to give sites names) but hammockforums is a wealth of knowledge...anything else ya need dont hesitate to ask me.... hey and if theres not many trees, and u got any rock climbing nuts(chocks) or cams you can highly increase your "hanging" spots.. rock-to-rock or tree-to-rock
