Custom Size 13ft x 15ft x 19.8ft Blue Right Triangle Sun Shade Sail

Our review finds the Custom Size 13' x 15' x 19.8' Blue Right Triangle Sun Shade Sail is best for homeowners and small commercial spaces that need reliable UV protection with a tailored fit. In this review the biggest reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and reinforced hardware that delivers true 95% UV blockage and measurable cooling without sealing out air or water, so it protects while still allowing airflow and some rain through.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, keeping shaded areas safer for people and pets.
• Temperature reduction: The sail can lower ambient temperatures by up to 15 degrees compared with unshaded spots, making patios and play areas noticeably cooler.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and increase the canopy's usable life.
• Custom sizing: The sail is made to measure from D-ring to D-ring, allowing a precise fit for odd-shaped spaces or retrofit installations.
• Permeable design: Water and air permeability prevent ponding and maintain airflow so the cover does not trap heat or collapse in wind or rain.
• Simple installation: It installs to trees, roofs or posts using mounting hardware kits and recommends specific D-ring to pole gaps for best tensioning.

Who It's For

The shade sail is aimed at homeowners, gardeners, and small business owners who want a heavy-duty, custom-sized shade solution for patios, play areas or animal enclosures. It suits people who value long-term durability, UV protection and a cooler outdoor space without a solid roof.

Those who need a completely waterproof canopy, an off-the-shelf standard size, or who prefer a very lightweight temporary cover should look elsewhere; this product is intended as a semi-permanent, tailored shade solution rather than a thin temporary tarp.

Pros & Cons

Pros

• High UV blockage provides strong sun protection for people and pets.
• Robust hardware and reinforced stitching improve longevity and resistance to wear.
• Custom sizing ensures a precise fit for irregular areas or specific mounting points.
• Allows airflow and water permeability to prevent pooling and reduce heat buildup.

Cons

• Some buyers report the finished product can feel smaller than expected, so careful measuring is essential.
• Not fully waterproof, so it will not replace a solid awning for complete rain protection.

Frequently Asked Questions

Will this sail block rain?
The fabric is water permeable, so it will not keep all rain out but prevents pooling and allows runoff.

How should I measure for a custom fit?
Measure from D-ring to D-ring at each corner and confirm the recommended gap to poles or anchors; the maker customizes to those dimensions.

How durable is the hardware?
The sail uses stainless steel D-rings and reinforced double-layer stitching designed for commercial-standard durability and comes with a 3-year assurance.
