I've had mesh tarps made from the same fabric as this sail hanging around my Endless Pool for a few seasons now, and they show NO signs of weather damage. It's amazing! I was happy to find the same fabric available in a larger size as a Sail.
I have an open carport, and this giant will cover the entire end and protect my vehicles and stored items from the sun & rain. It's very well made (unlike the cheapo versions I've bought in the past). No runaway or missing stitching,  the corners are reinforced/banded, and the "D" rings are plenty heavy duty. The color options even made it possible for me to match all of the sails/tarps to the roof of my yurt :).  Recommended.
