I have an older cover for my performer that's on it's last leg. it's a fairly heavy material vinyl or vinyl like material. I checked out a new cover & it's a super light weight material. it feels just like a generic cover that I bought at lower for $12.00 ( now $14.00 ) that I put on my good one open range smoker. the generic cover(s) lasted a year. BUT-it has a 3 year warranty so i'm on my 3rd cover for the same money. this cover has Velcro cinch straps at the corners & is a good fit on the performer. it actually fits a little better as I have a Cajun bandit smoker sitting on top of the kettle. I think i'm going to go this route instead of paying $40.00 more for near the same cover with a weber logo.
