A double-top canopy sheds heat and wind pressure more readily than a single layer, and on this 9.5-foot cantilever umbrella it sits above a rustproof aluminum pole with eight metal ribs that resist cracking or deformation. The foot pedal turns the shade horizontally through 360 degrees to follow the sun without moving the frame. Drizzle-resistant polyester handles weather, opening takes two quick steps, and durable rib pockets hold each rib firmly. A cross base is included for added stability, and a strap makes storage tidy. Overall 9.5 by 9.5 by 8.5 feet, folding to 3.3 by 3.3 by 8.2 feet; 39.5 pounds. Weighted base sold separately.
