I just knee jerked it, trying to avoid having one more thing to pack and carry.
Having things skate around on my kitchen counter tops really pushes my button when I want to focus on food prep.
It ain't a Luge track and people are hungry.
I love that mesh slip/grip stuff. Have used it for years on my wood carving benches. Buy a roll >> 16" x 24" pieces. I use both black and white.
When it gets really crapped up with dust, you can wash it in the sink with hot soapy water, wring it out and hang it up to dry = good as new for sticky.
I cannot tell you how much moisture it might wick up on a tent floor. But I agree +1 with Nice65 = your bed won't move.
Actually works rather well as a drawer liner in the kitchen, too.
