After many years sleeping on closed-cell foam, I finally am sleeping on an air mattress (POE Ether 6)...And now my back doesn't hate me anymore.
Problem is, now I worry about it puncturing.
Is a single layer of Polycro groundsheet enough to protect my air mattress from punctures? I did that on my last trip, but it had me shaking in my boots! Is the Polycro really puncture resistant enough?
Of course, it's only a problem when I go tentless. (When I have my Tarptent Squall, there are two layers protecting my mattress: The Squall floor, plus a layer of Polycro under that.)
