11 ft x 13 ft x 17 ft Green Right Triangle Sun Shade Sail - Durable UV

Our review of this 11 ft x 13 ft x 17 ft green right triangle sun shade sail finds it best for homeowners and small businesses who need a low-cost, effective sun cover for patios, pools, or carports. The single biggest reason to buy is its fabric performance: made from virgin polyethylene with strong tensile strength, it blocks up to 95% of UV and about 90% of visibility while remaining lightweight and ventilated, so shaded areas stay cooler without trapping heat. Installation is straightforward for DIYers, and the slightly curved edges help prevent sagging for a cleaner look.

Key Features

• Corner-to-corner measurement: The size is taken from corner to corner so customers can plan coverage precisely for irregular outdoor spaces.
• Curved edges design: Edges are slightly curved using a calculated radian to reduce sagging and keep a taut, attractive canopy.
• Virgin polyethylene fabric: Lightweight yet strong material delivers durability and resistance to stretching while remaining easy to handle during installation.
• High UV and visibility blockage: Provides up to 95% UV blockage and about 90% visibility blockage to protect skin and reduce glare around pools and patios.
• Seasonal versatility: Offers shading and cooling in summer, ventilation to avoid heat buildup, some rain resistance and anti-frost benefit at night.
• Warranty and customization: A 3-Year Limited Warranty and available custom orders make it suitable for tailored outdoor projects.

Who It's For

This shade sail is aimed at homeowners with patios, balconies, swimming pools or carports who want a proven fabric that blocks sun effectively and keeps outdoor areas cooler. It also fits gardeners and small business owners who need an inexpensive, durable cover that can be mounted between trees, posts or existing structures.

Those who should look elsewhere include buyers who need guaranteed full waterproofing for heavy rainfall or those requiring a rigid, framed awning; this product is slightly rainproof but is primarily designed for sun protection and ventilation rather than complete rain shelter.

Pros & Cons

• Durable virgin polyethylene fabric combines strength and light weight for easy handling.
• Curved edge construction prevents middle sagging for a neat, taut installation.
• Good value and longevity with customers reporting season-long durability and a 3-Year Limited Warranty.

Cons

• Hardware included receives mixed feedback, so buyers may prefer to upgrade mounting fittings for long-term tensioning.
• Not fully waterproof in heavy storms, so it may not replace a rigid canopy for continuous rain protection.
