Custom Size 11ft x 20ft x 22.8ft Waterproof Red Triangle Sun Shade

In this review of the custom size 11ft x 20ft x 22.8ft red triangle sun shade sail, the bottom line is straightforward: this is a practical, heavy-duty shade for homeowners who need reliable UV protection and water resistance for patios, carports, or yards. The reviewer found the sail especially useful where a robust, economical canopy is needed, since the polyester fabric with PU waterproof coating keeps rain and wind from passing through and the UPF50+ fabric blocks a large portion of UV rays. Assembly is simple and the reinforced corners make mounting feel secure.

Key Features

• Waterproof material: The polyester with PU waterproof coating prevents water and wind from penetrating, keeping the shaded area dry during light rain.
• High UV blockage: The fabric blocks up to 90% of harmful UV, offering strong sun protection for patios, carports and outdoor seating areas.
• Temperature reduction: The sail can lower the perceived temperature under the shade by up to 15 degrees, making outdoor spaces noticeably cooler.
• Reinforced edges and corners: Dual-layer white webbing and curved edges increase durability, and stainless steel D rings provide sturdy anchor points for installation.
• Quick to remove: The canopy can be taken down or pulled up in about five minutes, which is convenient for seasonal use or storage.
• Three-year limited warranty: The product includes a warranty that covers certain defects for increased buyer confidence.

Who It's For

This product is aimed at homeowners and small-business owners who need a reliable, commercial-standard shade sail for seating areas, carports, or garden spaces and who value waterproof performance alongside UV protection. It suits people who want a large custom-size triangle shade that is relatively quick to install and that holds up to sun and wind when anchored correctly.

Those who should look elsewhere include buyers seeking a lightweight, decorative-only canopy or those who require rigid, permanent roofing - this is a flexible fabric sail intended as a removable shade solution rather than a fixed structural roof.
