This sun blocker shade sail will not only block 80-95% of harmful UV rays, but will add style to your outdoor living areas. These sun sails are made of high-quality fabric and resist any form of fading typically caused by the sun. The fabric will not deteriorate with exposure to the elements, as water and wind easily pass though the fabric. The woven construction and reinforced edges prevent the shade sail from ripping. The UV blocking canopy is mounted through tension on (4) corners, equipped with a durable, heavy-duty stainless-steel D-ring. Nylon rope included to easily hang the sunshade from a wall, post, or tree. The shape allows for versatile placement and the concave edges prevent pooling and sagging.
