Light as AIR - Great Pad!
So far this pad has been amazing! Light as a feather and comfortable as all get up. I make sure to not over inflate it and it gives to make for a very comfortable sleep that works over lumps and rocks. I have been using a thin pad underneath that protects it from rocks as I am sketched out about punctures. I got the Large and would get the Medium if doing over. This is because it takes a long time to blow up and is a challenge to fold up. I keep it folded in thirds, as it comes from the manufacturer, and this seems to be the best way to store it. I would like to know if it can handle being used directly on stones but don't want to deal with punctures if it blows, so will keep using my super thin foam pad to keep the NeoAir off the stones. I used it nightly for two weeks on a glacier in Alaska and then again on a four day ski tour in the Wind River Mountains as well as several nights car camping with my son, and I sleep great with the NeoAir.
Bottom line...an amazingly light and comfortable sleeping pad that I highly recommend. If camping on sharp stones, I recommend bringing something to insulate the pad from the stones. A tent floor will probably suffice. I have been using the floorless Black Diamond MegaLite Tent...
