9ft x 13ft x 15.8ft Gray Right Triangle Sun Shade Sail - 95% UV Block

Our review of this custom size right triangle sun shade sail finds it best for homeowners or small-business owners who need a tailored, high-coverage shade solution. The biggest reason to buy is the combination of heavy 200 GSM HDPE fabric and a claimed 95% UV blockage, which delivers noticeably cooler, safer outdoor space while remaining breathable and water permeable. Installation is flexible enough for patios, playgrounds or poolside areas where anchored corners can be placed on trees, posts or walls.

Key Features

• 95% UV protection: The 200 GSM HDPE material blocks up to 95% of harmful rays to reduce sun exposure during long periods outdoors.
• Temperature reduction: The shaded area can be up to 15 degrees cooler than unshaded spots, making patio and poolside time more comfortable.
• Custom sizing: Made to order from D-ring to D-ring so the sail fits irregular spaces and can be adjusted for a neat, tailored look.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve long-term strength under tension.
• Breathable and water permeable: The fabric sheds some water while allowing airflow to avoid heat traps and reduce wind load.
• Flexible mounting: Can be attached to trees, walls, roofs or poles with common mounting hardware kits for many installation scenarios.

Who It's For

This shade sail suits homeowners, small commercial spaces, and anyone who needs a non-permanent canopy that fits an odd-shaped area; the custom D-ring sizing is particularly useful when exact coverage matters. It also works well for people who want a breathable fabric rather than an impermeable tarp, since airflow and water permeability can help with comfort and drainage.

Those seeking a lifetime, maintenance-free cover should look elsewhere; some users report mixed long-term durability in very harsh sun, so if you need a permanent architectural canopy or require full waterproofing, consider a different commercial-grade system or a solid roofed structure.

Pros & Cons

Pros

• Strong sun protection with 95% UV blockage for safer outdoor use.
• Custom D-ring to D-ring sizing yields a good fit for irregular installations.
• Stainless steel D-rings and reinforced edges give solid build quality and installation confidence.
• Air and water permeability improves comfort and reduces wind strain compared with sealed covers.

Cons

• Durability reports are mixed; heavy sun exposure may shorten service life for some installations.
• Not fully waterproof, so it will not replace a solid awning in heavy rain protection scenarios.

Our Verdict

Frequently Asked Questions

Is this sail waterproof?
It is water permeable rather than fully waterproof, so it sheds some water but will not provide complete rain protection like a solid roof.

How should I measure for a custom fit?
Measure from D-ring to D-ring at the planned anchor points and provide those exact dimensions to ensure a precise fit for your anchors.

Can the sail be attached to trees or posts?
Yes, it is designed for flexible mounting to trees, roofs, walls or poles using standard mounting hardware kits and leaving recommended gaps at corners.
