This cover has very thick material.  I sprayed it with a ton of Scotch-guard right away.  After the first rain, a few gallons of water were resting on top of the cover and hadn’t seeped through.  I’ll have to find some way to prop it up so the rain slides off instead, but I’m happy with it!  I also like that the colors and design are appealing and not just a big blob in the yard.  Replacing my old Tommy Bahama cover and so far I like this one better.
