I've been wearing them for a couple of weeks so can't comment on durability. However, the material feels durable and definitely waterproof. The elastic is very good quality, strong. No wind will blow it off the wheels. But if that were the case, the strap underneath would keep him on the quad. I have a rack and as you can see in the picture the cover fits over the entire quad (2020 Polaris 570) easily.
