When we started our hike in March we each carried a Big Agnes 2" air core pad. Very nice but just too heavy, and when I was so exhausted in the evening, having to face blowing that thing up was daunting. I'm setting out again in April and I don't want to carry that mattress. I have a Thermorest Z pad but when I try to sleep on that (or a 1" thick self inflating pad) I spend the entire night doing the rotisserie - turn from side to back to side to front to side .........and I don't sleep. I want a comfy pad that doesn't weigh as much as the Big Agnes. Does one exist??? I am 4' 10" tall and weigh 120 lbs if that's any help.
