A silver coating on the underside of the polyester canopy reflects heat as well as blocking UV, giving UPF 50+ protection across a 6.5 ft span. Eight fiberglass ribs flex in a gust instead of snapping, and an aluminum pole keeps the whole umbrella at 3.5 lbs so it can be carried to the sand with a chair in the other hand. Stands 7 ft high. A carry bag is included; a weight base is not.
