I have the small, original NeoAir, for some reason, the way the tubes run, makes it more comfortable than my older, regular LE. If nothing else, get it for the comfort level. I was letting some air out when I went to bed because of my shoulders, but now I leave it fully inflated. Like the rest of our gear, it doesn't work for everyone. Cascade Designs had some defective NeoAirs like the other companies pads. They do have great Customer Service as I have been on the receiving end a few times. I'm wanting a Xtherm later for winter snow camping, maybe when REI has a sale this Spring, missed out on the EB sale.
