The cover for my Genesis grill is awesome! It’s lightweight but strong. And it stays on even in the high winds we get here in New Mexico during the summer monsoons. And the rain just beads right off it.
It's rained since I bought it and water beads nicely, does not blow off in the wind due to the velcro cinches on each side. Too soon to see how it holds up. Wish it was a little heavier material.
Cover fits the grill very well, but the material is thin and I would suggest adding a "handle" to the top of the cover in order to hang the cover on a hook when the grill is in use.
