Right Triangle Sun Shade Sail 11ft x 21ft x 23.7ft Grey - Cool

In this review of the right triangle sun shade sail, the bottom line is simple: it is for homeowners and small commercial spaces that need a durable, highcoverage shade solution with strong UV protection. The reviewer found the custom size 11' x 21' x 23.7' useful for patios, play areas, and seating nooks, and the single biggest reason to buy is the fabric's combination of 95% UV blockage and heavy 200 GSM construction, which delivers reliable shade and temperature reduction without feeling flimsy.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, making outdoor time safer for families and guests.
• Temperature Reduction: The sail lowered shaded-area temperatures by as much as 15 degrees compared to unshaded spots, improving comfort on hot days.
• Custom Fit: Measured from Dring to Dring, the sail can be ordered to fit specific spaces and the manufacturer offers straight edge customization on request.
• Durable Construction: Reinforced edges, double stitching and stainless steel Drings create a robust perimeter that resists fraying and handles wind well.
• Flexible Installation: The sail installs to trees, poles, walls or roofs and works with mounting hardware kits; installers should leave the recommended corner gap for best performance.

Who It's For

The sail suits homeowners who want a substantial, visually neat shade for patios, poolside lounges, or childrens play areas, and for small businesses needing a costeffective canopy over seating. People who value durability and measurable sun protection will appreciate the heavy 200 GSM fabric and stainless steel fittings.

This is not aimed at someone seeking a temporary, ultralightweight cover for occasional use; those buyers should consider lighter, less costly options. Also, if exact offtheshelf sizing is essential, expect to verify Dring measurements carefully because customer feedback shows perceived size can vary versus expectations.

Pros & Cons
