Been lurking for a while trying to read up before I start asking questions and get the "use the search" responses. I love backpacking but my back has become a lot more fitfull lately. I'm trying to lighten my pack by ditching the tent. I'm also hoping the hammock will be more comfortable.
I have to say I'm a bit confused about the underquilt/pad thing. I plan on using my 25 degree sleeping bag, so how necessary is a pad or UQ? I typically only backpack in the western Sierras in the summertime. I do have a 3/4 length thermarest pad that I can use, or would a closed cell foam pad be better?
