MATERIAL: - The shade sail is made of 100% 185gsm high density polyethylene fabric, with strong stitching and durable stainless steel D-rings. The fabric is breathable and blocks 98% of UV rays, allowing air and light to pass through for a more comfortable space. WATERPROOF: - Allows cool breezes and light to pass through to create a more ventilated and comfortable space. Allows rain to pass through so water doesn't pool (so it's not waterproof) EASY TO USE: - Attach the shade sail's D-rings to your structure using the ropes provided. The sun shade cloth is easy to clean with mild detergent and water, fade resistant, does not stain or tear. APPLICATION: - Widely used for patio, outdoor lawn, garden, swimming pool, BBQ areas, pond, deck, courtyard, yard, gate, park, carport, pergola, sandbox, driveway or other outdoor occasions.
