I have been buying the grill manufactures covers in the past and they always fall apart in a year or so. 
This time I decided to try the Classic Accessories cover. As soon as opened the package I could tell the differance in quality. It's a very well made heavy duty material with a vinyl lining. It looks like it will last many seasons. It fit my grill perfectly.
If there is down side ,being a heavy quality material with a elastic bottom, its harder to place the cover on than the other covers I have had in the past. But it's deffenitly worth it. 
Highly recomend this grill cover.
