So far, I like the way the NeoAir sleeps - but all the sleeping so far has been in warm weather. I'm seriously thinking that the spare pad in the car, when I try the NeoAir in the cold, will be my tried and trusted Prolite 4 (I think they call it Prolite Plus now.) That pad has been under me in some 20-degree weather, with no problems whatsoever.

I like the NeoAir's additional comfort, and the half pound of weight it saves, but I am worried about cold-weather performance and long-term durability. At the first sign of trouble, I'm headed straight back to the Prolite 4.
