Custom Size 13ft x 17ft x 21.4ft Right Triangle Shade Sail - UPF50

In this review the focus is a custom right triangle shade sail sized 13' x 17' x 21.4', offered to be made to order for specific outdoor areas. The bottom line: this shade sail is for homeowners, small commercial spaces, and hobby livestock keepers who need a sturdy, UV-blocking canopy that reduces heat and fits a particular layout. The review highlights that the single biggest reason to buy is dependable sun protection from a 200 GSM HDPE fabric that claims up to 95% UV blockage while remaining water and air permeable.

Key Features

• 95% UV Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, providing reliable shade for patios, play areas, or runs.
• Temperature Reduction: The sail lowers ambient temperatures by up to 15 degrees compared with unshaded spots, which makes outdoor time noticeably cooler.
• Custom Fit: Measured D-ring to D-ring so the canopy can be made to match a specific triangular area for a clean, tailored installation.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings contribute to longer life under sun and wind.
• Permeable Design: The fabric is water and air permeable, so it reduces heat without trapping moisture under the canopy.
• Included Assurance: A three-year assurance is provided, which supports the stated commercial-standard build quality.

Who It's For

This shade sail is best for people who need a custom-shaped canopy for a specific corner or triangular area: backyard patios, small cafe seating, garden play areas, and even chicken runs have been cited by users who found the material effective. It is also suited to buyers who value long-lasting hardware like stainless steel D-rings and reinforced stitching.

Those who should look elsewhere include shoppers who want a full waterproof tarpaulin rather than a water-permeable fabric, or buyers who need a stock size with no lead time; this product is made to order and requires precise D-ring measurements for a proper fit.

Pros & Cons

Pros

• High UV blocking capability gives significant sun protection for comfort and skin safety.
• Permeable weave helps ventilation and prevents pooling when it rains.
• Sturdy hardware and reinforced edges increase longevity in outdoor conditions.
• Custom sizing allows a tailored fit for irregular or triangular spaces.

Cons

• Because it is made to order, size and measurement accuracy are critical; customers noted issues when the delivered sail felt smaller than expected.
• Not fully waterproof - it is designed to be water and air permeable, so it will not provide dry coverage in heavy rain.

Our Verdict

For anyone needing a custom triangular shade that prioritizes sun protection and airflow, this made-to-order sail represents good value because of its durable 200 GSM fabric, reinforced hardware, and measurable fit.

Yes; the sail is suitable for attachment to trees, roofs, walls or poles using appropriate mounting hardware kits and spacing recommendations.
