The vinyl is SUPER quiet. It almost feels more like a rubber compound so the wind and rain doesn't make any noise at all. Also I designed it with the screen like or mesh material so the wind goes through it rather than making it flap around or move in the wind. In the process I have found that the dirt dries up and kind of sifts through it as well so you don't have to dump it very often. It stops any clumps of dirt, but the fine stuff that turns to sand goes through.
I've had one in the woods for over a year and none of the critters have found a liking to it yet either. My padded seat is another story!!!
