I agree.
Nice find & I need more covers.
I got a "great" deal on some round kettle covers made of what feels like good material at Wallymart that were clearanced for more than your find, so I bought all they had left.
They fit up to a 30 inch grill diameter & have a cinch at the bottom, so I thought-perfect, even fits a 26 incher (that I don't yet have). After I got home, I noticed the dimensions says they are only 25 inches tall. In other words, they are basically a mini skirt for a kettle grill. I laughed. Then, I opened one for use on my old style Jumbo Joe & will return the rest, unless I can think of something else I'd use any for.
