Well I tried the X wave out. The first 3 nights I had very nice ground to sleep on and with this pad all was good. I didn't roll off which I found surprising. I'm always looking for my pad in the middle of the night. The true test was the final night, the back of my truck. I never felt the bumps in the truck bed,at all. It was great. It is much thinner than I expected. So easy to inflate and comes with a pillow. I think I have a winner, finally! No longer need 2 pads for comfort, dropped a lot of bulk and shaved off more weight!
Some heaveir folks seem to have issues with 'bottoming out'. Not so for me. Stomach sleepers do not like the pillow.
FWIW: I am a side sleeper, roll around a bit, 6 ft, 180lbs.
