There's no doubt a trade-off of expedition vs lighter-duty backpacking and comfort, in the sense that someone on an expedition or bigger mountain is more likely to want bombproof (closed-cell) and sacrifice comfort or squishiness.
Is Evazote similar to the typical blue closed cell foam pads you can get anywhere, or is it a more highly developed form of the species?
I have used normal Thermarests (not NeoAir) a fair amount for tent camping satisfactorily - don't really understand why they would fail quickly when used for that. Pinpricks in them can be sealed with seam seal without a patch, but finding the location of the pinprick out in the BC could be annoying and I'm glad I haven't had to do that. If I was going to use one on dirt/rocks without a tent, I would carry a tyvek groundsheet to limit abrasion damage.
The true inflatable pads, not thermarest but the air mattress kind, have a great weight/size tradeoff but they make me nervous and I've seen a couple of friends get leaks. I've been too cheap to try one anyway.
