Michael Ray, I think I see, you drop the inflation WAY down, at that point I'd rather be on a well inflated prolite, now I see. However, since hitting my hip bone never was an issue for me on any other thermarest foam core pad, I will assume there is some difference that isn't obvious and that we aren't actually aware of re our sleeping patterns.
Nick, your formula, complex as it is, if I grasp it correctly, is the essence of my problem with the neo air, that formula fails, and becomes: wake up every time I move, wake up to readjust the pressure, wake up missing a bad foam pad, curse the pad for sucking worse than anything I have ever used, all night, so clearly while your formula is correct, what lets you achieve that goal differs. For me, the neoair is an obstacle to achieving this simple goal, not a solution, so I really wonder what the differences are. there's no over thinking going on here, it's simply a basic wondering how experiences can very so widely, and reading others and just not getting it.
I'm just going to leave this a mystery, though I will try it on one more over nighter, letting it basically be almost flat, with very little r value, and see if that works better, but I doubt it will since I tried most possible levels of inflation on the 5 day trip just to be fair, but I may not have gotten close to it being essentially flat, with just enough to hold the side hip 3/4 inch over the ground.
What I find odd is that everything people say they like about the neoair is what I would say about the prolite, even the short version.
Re the durability, holes, punctures, are always user error, I don't blame any pad maker for a user putting it ontop of something sharp (did I tell you about the time I was using the old heavy thermarest strapped to the side of my pack and on a very hot day, climbing a very sun exposed hill, I stumbled into one of those beautiful dry climate plants that have a sharp needle point at the end of each of their long thin leaves? Went through I think 5 layers of the rolled pad...). The only thing I'm noting is the actual statistical failure rate of the seams themselves, and statistical does NOT mean, it's never happened to me, it's an average. For some reason this is a hard thing for people to get, not sure why, if it never happens to say, 98% of people, then you are very likely to never have it happen to you. What interests me is the cases where it does happen, and happen repeatedly, to people, such as german tourist, who seems to have that german analytical quality down well enough to be worth paying attention to in their reports on gear.
But thanks especially michael, given this was a test purchase, and it was off of gear swap, and it will go back on gear swap when I finally give up on it, I am interested to see if I can ever get something even close to a good night's sleep on it, but also given that the prolites already do that, and do it much more conveniently, maybe I shouldn't think about it anymore and just sell the neo air this spring...
I'll make one more guess: with proper extra inflation, the prolite isn't going to give you hip bone protection as a side sleeper if you weigh more than 160 pounds, give or take. I weigh a bit less than that it and does, without a doubt. So interesting views, maybe the world is separated into people who can sleep on a non filled core air mattress and those who can't, and there's really nothing more to it.
