Im going on my second year with my "xlite" & I just kick the rocks & sticks away just like if I used a foam pad. No problems so far, but if I ever wake up on one that went flat, Ill be one mad mf!Does anyone have a problem with tearing air mattresses when setting up on rock sprees? I guess I'm just old fashioned or pig headed, I still run a closed cell foam mat. It's a little bulky but weighs less than a pound and if I lay it on a sharp rock by mistake no harm done, just move the rock.
