Polyester is water-resistant, which makes it a great choice for humid or rainy conditions and it’s easy to clean. Sunscreen coating: The silver coating of this sun shelter absorbs more light and protects your skin more effectively. Full cover protection: This outdoor parasol includes two side walls that can be disconnected easily and connected with a panel by hook-and-loop fasteners, allowing the sun shelter to modify the angle and direction to suit varied situations and provide additional shading options.
