17ft x 20ft x 26.2ft Gray Right Triangle Sun Shade Sail - Custom Fit

In this review the Amgo custom size right triangle shade sail is judged on fit, protection and durability for homeowners and small businesses who need a tailored sun cover. The bottom line: it delivers strong daytime sun protection and a noticeably cooler shaded area thanks to its 95% UV blockage, and it is best for people who can install anchors or use basic hardware to tension a sail precisely. It is less suitable for someone wanting an off-the-shelf umbrella replacement with no custom measuring or assembly.

Key Features

• High UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays so outdoor areas stay safer for long periods.
• Temperature reduction: Expect up to about a 15 degree reduction under the sail compared to unshaded spots, making patios and play areas more comfortable in heat.
• Custom sizing: Made to order from D-ring to D-ring so the sail fits a specific space rather than forcing the space to fit the product.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resist fraying at stress points.
• Permeable design: The material is water and air permeable so wind load is reduced and light rain typically passes through rather than pooling.
• Three year assurance: The product includes a 3 year assurance for the buyer, providing some coverage against problems in typical use.

Who It's For

This shade sail is aimed at homeowners, cafes or small commercial venues that need a tailored right triangle canopy to cover an irregular area, and who can measure between anchor D-rings accurately. Installers who want a breathable, heavy-duty fabric that reduces temperatures and blocks most UV will appreciate the 200 GSM HDPE material and reinforced hardware.

It is not ideal for buyers who want an instant pop-up solution or those unwilling to plan anchor points and leave at least 0.5 ft gaps at corners; people needing a fully waterproof canopy should look elsewhere because the sail is water permeable rather than watertight.

Pros & Cons

Pros

• Excellent sun protection with up to 95% UV blockage, which makes it effective for long outdoor exposure.
• Custom sizes ensure a close fit for odd-shaped patios or shade needs without unnecessary excess fabric.
• Sturdy build with stainless steel D-rings and double stitching addresses common wear points.
• Permeable fabric reduces wind strain and prevents water pooling during light rain.

Cons

• Durability reports are mixed; some users report long life while others experienced degradation after about a year, so heavy sun exposure can shorten lifespan.
• Installation requires planning and correct spacing of anchors, which may be inconvenient for casual buyers seeking a tool-free solution.

Our Verdict

It offers good value when properly measured and installed, though buyers should expect variable long-term durability in intense sun and plan for periodic replacement in those conditions.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring while allowing at least 0.5 ft gap between each D-ring and the anchor; reduce gap by 1 to 1.5 ft per side if needed for installation constraints.

Is the sail waterproof?
No, the fabric is water and air permeable so it does not form a fully waterproof canopy but does prevent pooling and reduces wind load.

Can I mount it to trees or walls?
Yes, the sail is designed to be attached to trees, roofs, walls or poles using appropriate mounting hardware and tensioning at the corners.
