I’m really pleased this fits my umbrella. Although the description states it’s rated for 12-14’ umbrellas, the cantilever arm on my Hampton Bay 11’ umbrella is much larger than other models pictured and probably the cover rated for that size might not have fit. It was easy to place and the zipper and nylon tie strap seem to be of quality. I am also happy with the color choice available, it nearly matches a patio table cover from another brand I have. I literally just received it in time for some thunderstorms so will test the water resistance. I don’t intend to leave the umbrella with cover outside when the weather turns to winter but the product ‘seems’ as if it would last quite a few years if taken care of like you would the equipment it covers. It would not be fair to rate durability with this review.
