Custom Size 13 ft x 16 ft x 20.6 ft Waterproof Blue Triangle Sun Shade

In this review of the Custom Size 13' x 16' x 20.6' Waterproof Blue Triangle Sun Shade Sail, the bottom line is simple: this is a practical, heavy-duty shade for homeowners and small businesses who need dependable UV and rain protection. The reviewer found its single biggest selling point is the waterproof polyester with PU coating combined with reinforced edges, which delivers reliable shade and weather resistance while also lowering temperature noticeably under the canopy.

Key Features

• Waterproof construction: Polyester fabric with a PU waterproof coating keeps rain and wind from passing through so outdoor spaces stay drier.
• UV protection: The sail blocks up to 90% of harmful UV, making it a strong sun barrier for patios, carports, and gardens.
• Temperature reduction: Placing the sail over a seating area can lower the temperature under the shade by up to 15 degrees, improving comfort on hot days.
• Reinforced edges and corners: Dual-layer white webbing and stainless steel D rings at corners provide durability and secure mounting points that stand up to tension.
• Quick to install or remove: The lightweight design allows the sail to be taken down or re-tensioned in around five minutes for seasonal use or storage.
• Warranty: Comes with a 3 year limited warranty that covers manufacturing defects and gives buyers added confidence.

Who It's For

This shade sail is best for homeowners with patios, carports, yards or garden seating who want an economical canopy alternative that blocks UV and sheds rain. It also suits small commercial outdoor areas where a triangular configuration fits between posts or walls.

Those who should look elsewhere include buyers needing exact custom mounting hardware or rigid structures; this product relies on tensioned mounts and stainless D rings rather than fixed frames. People expecting a perfect size match should check measurements carefully, as some reviewers reported size expectations varied.

Pros & Cons

Pros
