Custom Size 11ft x 16ft x 19.4ft Right Triangle Shade Sail - UPF50

In this review the focus is a custom-sized right triangle shade sail intended for patios, playgrounds, and commercial outdoor spaces. The biggest reason to consider it is the fabric's high sun protection; crafted from 200 GSM HDPE with UPF50+ performance, it blocks up to 95% of UV rays while remaining water and air permeable. The review examines fit, ease of installation, and durability so buyers can decide if a tailored shade sail is the right solution for cooling and sun protection in their space.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of UV rays to reduce sun exposure for people and surfaces underneath.
• Temperature Reduction: In shaded areas the sail can lower ambient temperature by up to 15 degrees compared to unshaded spots, making outdoor time more comfortable.
• Customizable Fit: Measurements are taken D-ring to D-ring so the canopy can be tailored to fit awkward or nonstandard spaces precisely.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity and resist fraying under normal use.
• Water and Air Permeable: The fabric sheds some water while allowing airflow, reducing wind load and pooling compared with solid tarps.
• Easy Installation Guidance: The sail installs to trees, walls, roofs or poles and includes guidance to leave at least 0.5 ft gap at corners for optimal tensioning.

Who It's For

This shade sail is well suited for homeowners, small businesses, and schools that need a tailored sun protection solution for irregular spaces such as triangular courtyards, patios, or playground corners. It is especially useful where a cooler shaded area and high UV blockage are priorities.

People who want a permanent waterproof canopy or expect a maintenance-free lifetime product in extreme conditions should look elsewhere; while robust, the HDPE material is breathable and may need occasional replacement after extended, harsh sun exposure.

Pros & Cons

Pros

• Blocks up to 95% of UV rays for strong sun protection and safer outdoor use.
• Can reduce temperatures by up to 15 degrees, improving comfort under the sail.
• Custom sizing from D-ring to D-ring delivers a tailored fit for nonstandard areas.
• Stainless steel D-rings, reinforced edges, and double stitching enhance durability and reduce fraying.

• The breathable HDPE fabric is not fully waterproof and can show wear over many seasons in intense sun; some users reported varying longevity.

Specifications

Our Verdict

This custom right triangle shade sail is a practical value for anyone needing strong sun protection and a cooler shaded area in a nonstandard outdoor space. The tailored fit, high UV blockage, and solid hardware make it a sensible choice, though buyers should expect a breathable fabric that may show wear over multiple years in very harsh sunlight.

Frequently Asked Questions

Can this sail be attached to trees or buildings?
Yes, it is designed to be mounted to trees, roofs, walls or poles using appropriate hardware and by leaving the recommended corner gap.

Is the fabric fully waterproof?
No, the 200 GSM HDPE is water and air permeable so it reduces pooling and wind load but is not a fully waterproof tarp.

How is sizing measured for a custom order?
Sizing is taken from D-ring to D-ring so provide accurate corner-to-corner measurements for the tailored fit.
