BONOSUKI patio offset umbrella is more versatile than a regular market umbrella: there is no pole in the center that might block your view, allowing you to enjoy a larger area of unobserved shade. The canopy is made of UPF80+ yarn-dyed fabric, supported by 8 powder steel umbrella ribs, ensuring firmness and rustproof while providing you with smooth-touch and superior appearance.
