11ft x 13ft x 17ft Right Triangle Sun Shade Sail - 95% UV Blockage

In this review the 11' x 13' x 17' right triangle sun shade sail is judged as a practical, heavy-duty canopy for patios, chicken coops, play areas and small commercial spaces; its single biggest reason to buy is the reliable sun protection from 95% UV blockage while still allowing air and water to pass. The reviewer found the material and construction feel robust, installation is flexible for many mounting points, and the customizable D-ring-to-D-ring sizing is useful when a precise fit matters.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays for safer outdoor time.
• Temperature reduction: The shade can lower ambient temperature by up to 15 degrees compared with unshaded spots, making patios and enclosures noticeably cooler.
• Water and air permeable: The fabric sheds some water and lets air pass through, reducing wind stress and preventing puddling under the sail.
• Custom fit: The sail is cut to measure from D-ring to D-ring, enabling a tailored fit for irregular spaces or when one needs precise coverage.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings give the sail commercial-standard durability and a three-year assurance.
• Flexible installation: The sail can be attached to trees, roofs, walls or posts using mounting hardware and simple spacing guidelines to optimize tension.

Who It's For

The shade sail suits homeowners and small business owners who need heavy-duty sun protection over patios, play areas, outdoor seating or animal runs and who want a custom-sized solution rather than a one-size square. It is especially useful for those who value a breathable fabric that reduces heat while avoiding full waterproof covers that trap heat.

Those who need very large, fixed architectural awnings, fully waterproof canopies, or a ready-to-go kit with rigid poles included may want to look elsewhere, since this product is a fabric sail meant to be tensioned between existing anchors and is customized to the D-ring spacing provided.

Pros & Cons

Pros

• High sun blockage and measurable temperature reduction make it effective for cooling outdoor spaces.

Frequently Asked Questions

How should I measure for a custom fit?
Measure straight line from D-ring to D-ring at the anchor points you will use and provide those dimensions for customization; leave recommended clearances at each corner for proper tensioning.

Will it collect water?
The fabric is water and air permeable so it does not pond like solid tarps, but it is not fully waterproof during heavy rain.

Is the sail suitable for windy conditions?
Yes, the breathable HDPE fabric and reinforced edges reduce wind load, but secure, properly spaced anchors and occasional tension checks are advised for severe weather.
