As stated in the other reviews, this is a great pad but has quirk or two. On the up side it is light and really comfortable, IMO. Also it is great to deal with the GG UL geeks (love their Squall Classic tarptent). I like the egg shell surface, my partner doesn't. So there is some personal preference in this sort of thing.
It does give up some of its shape and "loft" after or with use. And, in my case, it got a tear in it at one of the folds after a bit of use, but that can easily be fixed with the duct tape solution.
I use it combined with the thin, smooth surface grey closed cell foam longer pad GG sells, which takes away the problem for me of needing the extra length ... but people taller than 5'10" may have a problem with it running short of the hips when it is up around the neck or head. I keep the top of the torso pad at my shoulders and then it reaches well enough below the hips ... but I also use some kind of pillow for my neck and head area, especially in warm weather when I using my less loft more thin REI sub kilo 32 down bag (1.5 lbs.) instead of the winter/cold weather Marmot Never Summer 0 degree F high loft, comfy, heavy and bulky, but so ever soft down bag (3 lbs. +).
Finally, I attached some velcro to the underside of the torso pad and the thin pad so they would stay in place together ... the velcro seems to come loose because it does not stick to the surface of the closed cell foam very well ... anyone have a solution for that?
So even with the quirks (which is why I give it a 4 rather than a 5) the GG pad is my favorite ... especially when combined with the thin longer pad. Without that thin longer pad I'd probly give the torso pad a 3 as others would.
All in all I am sold on closed cell foam for UL packing (knocks off a bunch of ounces from the pack weight) ... otherwise I really like the inflatables with down or foam in them (like the Big Agnes black thing which I use a lot for car camping or if guests have to sleep on the floor).
