I ordered this umbrella specifically because it is a Sunbrella fabric.  I've only had it up for 1 week so I don't have any information on fabric fadig or durability.
Here's the catch...   I ordered a purple (Iris) umbrella.   It came with RED stitching.  Twice.   As always, Wayfair's customer service is fantastic!   I would have expected the thread  to be the same color as the fabric... and as shown online.
Umbrella is otherwise attractive and seems sturdy.

Color looks good after 1 season.
