i'm not sure i'm ever getting an underquilt. the blue pad's bulky, but very light and durable. my only real complaint is the comfort under my heels. this has me interested in a textured pad like the z-lite or ridge rest.

however, i just ordered a new sleeping pad: the alps mountaineering comfort series. it's a thermarest-type, self inflating pad. i actualy got it for the ground since my next trip looks like i'll be stuck in wide open space, but i'm eager to try it in either of my hammocks.
