I would be surprised if you find a better cover than the grillstuff cover. It is top notch. Hands down the best SSP out there.
@Bob BQ, how long can I expect it to last? My grill is always outdoors, North Georgia....so mild winters, extreme heat in the summer. I ask, because I want to know if I should get a backup. Finding covers for the SSP is getting increasingly difficult.
I can't say how long it will last, but mine has so far withstood both hot summer weather and freezing cold. No drying, cracking, ripping, stretching, shrinking, etc, so far. As
@WEBERNV said, it is very heavy duty material.
