Right Triangle 11 ft x 13 ft x 17 ft White Sun Shade Sail - Heavy Duty

In this review of the Right Triangle 11 ft x 13 ft x 17 ft White Sun Shade Sail, the bottom line is simple: this shade sail is for anyone who needs dependable UV protection and a tidy installed appearance for patios, play areas, or dog runs. The reviewer found the sail's biggest advantage to be its combination of heavy duty 200 GSM HDPE fabric with a measured curved-edge design that keeps the sail tensioned and prevents sagging, so it stays neat and performs well under sunlight over time.

Key Features

• Curved edge measurement: Corners are measured corner-to-corner and edges are cut with a calculated radian so the sail tightens evenly and resists mid-span sagging after installation.
• 200 GSM HDPE fabric: Made of 100% high density polyethylene, the woven knitted material blocks up to 95% of harmful UV while remaining breathable so air and light pass through.
• Breathable, water-shedding weave: The fabric allows water and breeze to pass, which reduces pooling and lowers wind load compared with solid canopies.
• Reinforced corners and hardware-ready: Heavy duty double-layer stitched seams and extra corner stitching protect stainless D rings for secure mounting and long life.
• Three year UV warranty: UV inhibitors are added during manufacture and the sail carries a 3 year warranty against UV degradation under normal weather.
• Custom edge option: If straight edges are preferred instead of the factory curved edge, a custom order is available on request.

Who It's For

This shade sail is best for homeowners and small business owners who need a durable, breathable shade solution for patios, playgrounds, poolside areas, or pet enclosures. Installers who value a neat, tensioned look will appreciate the measured corners and curved-edge construction that minimize sagging and make tightening straightforward with turnbuckles and cable.

It is less suitable for those who require a completely waterproof canopy or rigid structure, since the fabric is breathable and allows water through to avoid pooling. Anyone needing a very specific straight-edge aesthetic should request the custom straight-edge option before purchase.

Pros & Cons
