This waterproof triangle shade sail is a stylish all-weather outdoor shelter for your patio, backyard, poolside and garden. Constructed from heavy-duty polyester fabric with premium PU waterproof coating, it effectively repels rainwater and blocks up to 95% harmful UV rays, lowering surrounding temperature and creating a cool dry resting area. The triangular shape fits corner spaces perfectly and delivers elegant curved tension when installed. Double-stitched reinforced edges prevent fraying and tearing, and three corners are fitted with rust-proof stainless steel D-rings for stable tensioning. Every triangle shade sail comes with a complete hardware set including ropes and fixing accessories, no extra parts needed for quick setup. It is fade-resistant, mildew-resistant and easy to clean & store, ideal for residential outdoor recreation and partial shade coverage.
