SpaUmbrella designed especially for spas. Whether your escaping the snow, rain or bright sun, the 9 foot wide SpaUmbrella will keep you covered. Built with a wind vent for those breezy days and tested without failure in winds up to 25 mph. Convenient, easy-mount system...simply slip the umbrella base under the spa. No fastening to the spa. Special Sunbrella fabric for maximum sun resistance and years of trouble-free ownership. It's even machine washable. When not in use, SpaUmbrella folds up and swings out of the way.
