Staked one of these over the leaf pile through a week of steady rain and it held up with zero leaks. The 10x8 size covers a good chunk of ground, and the grommets didn't tear when I pulled the rope tight.

Tossed one over my firewood pile before a week of rain and it stayed bone dry underneath. The 8x10 size is just right for small jobs like that, and the material feels thick enough to survive being dragged around.

Used two of these to cover my camping gear through a rainy weekend and everything stayed bone dry. The 8x10 size is just right for wrapping a tent and a couple of coolers, and the material feels thick enough to survive being dragged around.
