- Virgin, UV stabilized 190 GSM HDPE material: The only sun shade sail on the market made from 100% virgin (non-recycled) HDPE. It has undergone 20,000 hours of laboratory UV testing and is proven to be about 70% more durable than recycled HDPE under sun exposure. The fabric is treated with a UV stabilized compound to prevent drying out, tearing and fading, significantly extending lifespan. - 95% UV blockage and breathable fabric: Blocks 95% of harmful UV and helps reduce temperature in the shaded area, ideal for patio, swimming pool, balcony, and carport. The breathable woven fabric allows water and air to pass freely, prevents pooling in rainy days, and is resistant to both UV and water with no ongoing maintenance required. - Durable construction: Edges feature heavy-duty, double-layer reinforced stitched seams to prevent frayed edges and loss of shape. Each corner ends with a stainless steel D-ring for easy hanging, with extra heavy stitching to securely attach the D-rings to the shade sail. - Installation guidance: Hardware kits are required and sold separately. Each D-ring requires one cable rope (do not use nylon ropes, as they break easily). Connect the opposite ends of cables to existing poles, trees, or walls using shade sail hardware kits. High-quality hardware kits and cables are strongly recommended for best performance and appearance.
