If you want something really minimalist, look at the Gossamer Gear Nightlight torso length sleeping pad. It's basically a torso-length version of the Thermarest ZRest. Probably the closest to the old Mt. Washington pad.

Next up would be a self-inflating mat from Thermarest such as the Prolite, definitely less bulky when packed than a full-length CCF pad and not needing the "huff and puff" routine..
