Designed with slightly curved sides to improve tension and reduce sagging, the sail is lightweight for easy transport but robust enough for seasonal outdoor use. It includes four 5-foot ropes and an instruction sheet so you can install it between posts, trees, or existing structures; leave 1.5–2 feet clearance for hardware or fastening.\u003c\/p\u003e\n\n\u003ch3\u003eHow well does this shade sail block sunlight and let air flow?\u003c\/h3\u003e\n\u003cp\u003eThe fabric is a 100% high-density 180gsm HDPE weave rated to block about 95% of UV radiation while remaining breathable.
