I used pads for a long time, blue ccf, then GG 1/4 evazote. I love the comfort of my underquilt, but I still carry the pad in case I need to sleep on the ground. I can fold the 1/4 inch in half and get through the night on the ground in a miserable sort of way. I use both for the hammock if it is cold enough. One of these days maybe I will have an underquilt for every season.
