Custom Size 11ft x 21ft x 23.7ft Blue Right Triangle Sun Shade Sail

Our review of this custom-size right triangle sun shade sail finds it best for homeowners and light-commercial users who need dependable sun protection and a tailored fit. The key reason to buy is straightforward: it offers substantial 95% sun protection from a robust 200 GSM HDPE fabric while remaining breathable and cooler than unshaded areas. Installers who want a precise D-ring-to-D-ring fit and reinforced hardware will appreciate the attention to construction and the option to request straight edges for a cleaner look.

Key Features

• High UPF protection: The 200 GSM HDPE fabric blocks up to 95% of UV rays, offering reliable sun protection for patios and play areas.
• Temperature reduction: The breathable material can lower surface temperatures by up to 15 degrees compared to unshaded spots, improving outdoor comfort.
• Custom fit: Measurements taken from D-ring to D-ring allow you to order a shade that matches your unique mounting points for a cleaner installation.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and strengthen long-term use.
• Flexible installation: The sail attaches to trees, roofs, walls or poles with common mounting hardware and allows corner gap adjustments for best tension.
• Commercial standard: Built to a commercial standard and sold as an order-to-make canopy, it suits both residential and light-commercial installations.

Who It's For

This shade sail is ideal for homeowners, small business owners or parks managers who need a tailored right triangle sail to cover an awkward space and want strong sun protection with breathable material. People who plan to anchor to fixed points and value reinforced hardware and the option to customize straight edges will get the most from this product.

Those seeking a temporary pop-up shade or a fully waterproof canopy should look elsewhere; this sail is water and air permeable by design. If absolute long-term UV endurance in extreme climates is required, consider monitoring longevity reports closely, as some users report variable lifespan in very harsh sun.

Frequently Asked Questions

Is this sail waterproof?
Answer. The fabric is water and air permeable, so it sheds some water but is not fully waterproof; it is designed to provide shade and airflow.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring at the anchor points you will use and include any required gap; the seller custom-makes to those dimensions.

How durable is the sail in direct sun?
Answer. Construction uses 200 GSM HDPE with reinforced stitching and stainless D-rings for durability, but long-term lifespan can vary with constant harsh UV exposure.
