The one I've been looking for
I've been looking for a do anything sleeping pad and this seems to be it. It's not as small and lightweight as the ultra light pads, but I can't sleep on those anyway. I went with the dual core to get the extra R value for cold weather camping and this delivered. I did an early October backpack through the White Mountains on the AT and found this pad to be a lifesaver on a cold-cold night in Imp Shelter. The low was below freezing (I'm guessing high 20's). Sleeping on the dual core, I barely noticed the cold, but when my knees and elbows ventured off the pad, I could really feel the change. The insulating value of this pad is remarkable. Pair it with a good sleeping bag and you're all set. It packs small (not nalgene small, but close) and 2-2.5lbs it's worth it's weight.
My only complaint - it does suck to blow it up, especially when you're cold and tired.
