This product is not very good. I order 6 weathermax covers for my $4k Adirondack chairs thinking these products would be the same quality as the custom chair cover I purchased recently and the sectional and coffee table covers I ordered from Koverroos a few years ago. Why Koverroos doesn't offer the elastic band as standard for ready made chairs is beyond me but I spent approx. $700 for these covers and I regret the purchase. Save yourself the trouble and don't purchase their ready made products...they are absolute crap! The only reason I'm giving 2 stars is the previous experience with purchased products. If this was my first purchase I would've looked for a different company.

I bought 2 of these 7 years ago & again today. I live in the Pacific NW & they cover my chairs year round. They are on my top deck & not under trees. Mostly they worked great but in the last year the fabric on the top section just crumbled away. Verticals sides are all still in pretty good shape. I also have this cover on table & chairs set on lower deck that gets more shade. The fabric there did not crumble but in the last year as the fabric weakened the squirrels found it was easier to pull apart & began extracting pieces. All told, 7 years in rain & lots of wind ... worked great, no mildew, no wet.

Replacing cover I've had for 12 gears

Excellent covers. Very sturdy. Where I live there is a lot of wind and sun; the covers have held up nicely

I rate these covers as excellent & well worth the price.
They come in a convenient bag.
They are easily folded & fit in the bag for storage.
They are thin, light weight, easy to handle & easy to place on the item during bad weather.
They have excellent clips to hold done on chair for
securing from the wind.
They shed water & wind & seem sturdy enough to
last many years. A season will determine their
ability to resist rips.
I do not know of the UV endurance. One or two
seasons will determine their performance.
I ended up ordering 4 total as I was pleased with the
first one.
