I too live in Louisiana and after having a bunch of scooter / motorcycle covers turned to paper from the UV rays I looked for something of a different material and ended up with this bicycle cover. It fits a little more tightly to my perspective so less billowing when it’s windy and it’s made of a thicker ripstop material. I’ve only had it for about 2 months but so far it looks great and I’m confident it’ll hold up much better.
