Poor quality. Zipper had several off set teeth that were sewn that way making it difficult to zip (pictures shows only one area there were several along the cover) and the elastic rope inside the hem to tighten the bottom, one rope end is trapped inside the hem. It moved but the end of the material where the hole would be was sewn shut. So when you’re pulling it shut to tighten the bottom it doesn’t work. See their catalog picture each side of the material on the each end has a hole where the rope comes out and is attached to the toggle to tighten the bottom. Mine isn’t attached to the toggle because there’s no hole for the rope to come on one side.  So I had to use a bungie cord. Pretty bad when you pay so much for a product.
