I've actually been impressed with my NeoAir. I slept on trash bags recently because I couldn't find my ground sheet. Trash bags are NOT a good idea. Very slippery. My NeoAir slid off during the night, and gravelly, coarse dirt ground into the underside. No holes.

I wouldn't recommend doing what I did! But they seem to be fairly tough.

I'd be very worried in areas with thorny or spiny plants, though.
