Not a weight saving even in the summer, because nights are often below 40*F and can easily get below freezing in the high mountains in the summer. So I'd have to take a 3/8 to 1/2" pad almost all the time.

I am comparing the weight (and comfort) of the NeoAir to a standard insulated air pad, such as the POE Ether Thermo and the BA Insulated air pad, which are the alternatives if you want a 2 1/2" thick air pad. I haven't been able to use a self-inflating pad for years--my hips have gotten more and more pressure sensitive.

How does one afford the NeoAir, assuming you would want it? REI has 20% off coupons several times per year, and allows you to return the thing even if you've used it on a couple of trips. Short size pad plus the 20% off coupon put it under $100.

I expect my next pad, once my POE pad dies, will be a custom down-filled pad, probably 3 inches thick, from Kooka Bay.
