Interesting experiment Walt. I got what I think was the original neo-air in 2009 and that initial pad has been replaced by them three times so far; every single replacement was at no charge and upgraded to the closest matching current model. Every failure was a pregnancy. The last pad in that chain was the yellow xlite that I still use after a bear stepped on it and punctured it two summers ago (and I patched it with Tear-Aid tape....still holding as of last weekend).

My winter top pad (that I use on top of the Solar ridge rest these days), developed a small bloat upon the fourth nights use which was extremely disappointing but so far has not gotten bigger.

Seems there is no perfect solution.
