the worst problem I had with my mesh floor, was when packing the tent up one morning. It was dry, very dry. Normally I fold the tent lenthwise so that the mesh is on the outside, and the cuben is inside, and its about 12" wide, then I roll it up.
On this particular very dry morning, static charge built up on the tent. The more I rolled it, the higher the charge was. Tons of little pieces of dry duff and pine needles clinging to the mesh by static charge, and standing on end like needles. Every 1/2 roll I had to wipe the stuff off with may hands, befor rolling another half turn. Wierd.
