Knit from durable high-density polyethylene (HDPE) without recycled content, the fabric balances sun-blocking performance and breathability so spaces beneath stay cooler without trapping moisture. Built with reinforced seams and rust-resistant hardware, the sail is designed for seasonal use and can be installed with standard anchors or SUNLAX accessories (sold separately).\u003c\/p\u003e\n\n\u003ch3\u003eHow well does this cover block sun and UV rays?\u003c\/h3\u003e\n\u003cp\u003eThe SUNLAX shade sail is engineered for strong UV reduction, offering approximately 90%–95% shading for most colors (80%–85% for the white series).
