However, I do think this material is puncture proof enough for my use. All my tents have floors, if not an additional 'floor saver' underneath and I spend some time making sure that nothing under the tent will damage the floor. Your situation may vary...
Sounds like you end up on the rocks, in which case this pad may not be for you. I suppose if we were real men, we'd cut some pine boughs and make a bed out of those, huh?
Yeah, well as Toby Keith says, "I ain't as good as I once was...." I'll pass on the pine bed.
I'm thinking of going with the light weight thermarests and a tyvek groundsheet. That should do it with the additon of a tent floor. That weight and comfort looks real attractive.
