This is sort of a long term test, since I've slept on this pad pretty much exclusively on a carpeted concrete floor for more than six months and have been using it as the second choice to my recliner for more than five years. I've used it on really rough outdoor concrete, and it shows zero signs of wear. My sleeping pad of choice is the Thermarest Military Trail Lite. I got it at the PX, and although it came along as issue gear long after I retired, I think it's pretty close to what is issued to the U.S. military. ( "Green side out, brown side out!") It's far superior to the bulky rolled up foam iso-mat, and the much hated inflatable "rubber bitch" that preceded it. I'd been issued both of those, as well as having several months experience in Northern Michigan and Southern Ontario as a bicycle bum with an old GI air mattress that seemed to know the precise second I would doze off, and at that moment, be completely flat, cold, and useless as anything but a ground sheet. Compared to military sleeping mats of the past, the Thermarest is a wonderful piece of gear. It will self inflate to a minimal level, but i usually give it a few good breaths to fully inflate it. After I'm settled I usually find full inflation to feel a bit tippy, like the first few seconds after getting into the canoe for the first time in the Spring. I release air from the valve to achieve maximum comfort. It's a lot like a sleep number bed; adjustable to your individual comfort level. Length is more than enough for me at a little over six feet. Width leaves a little to be desired. In the field, a couple piles of leaves or pine straw would keep my elbows off the deck, but on concrete I whip out some extra folded trousers or shirts to give me extended arm pads to the side of the 21" wide mat. I sleep with my pack under my knees to keep my back comfortable, and have been comfortable with this arrangement since October of last year. It's the first time I've been comfortable sleeping on a flat surface in more than 20 years, and probably one of the most comfortable ways I've ever slept. At almost two pounds, and requiring a little patience to get packed up small, it's a bug-out luxury if you're in a hurry and traveling light. In a car, or an extended travel bag, it's well worth the weight, tough, easily washed, it floats, and is likely adaptable to lots of other field expedient tasks.
