Custom Size 13ft x 16ft x 20.6ft Right Triangle Sun Shade Sail

In this review the Amgo Custom Size right triangle sun shade sail is judged primarily on sun protection and fit. It is aimed at homeowners and small commercial users who need a tailored shade solution for patios, play areas, or animal shelters. The single biggest reason to buy is its combination of near-complete UV blockage and a custom D-ring to D-ring measurement process that produces a close, secure fit for awkward or specific outdoor spaces.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays for safer outdoor time under the sail.
• Temperature reduction: The mesh fabric lowers ambient temperature by up to 15 degrees compared to unshaded areas, making patios and enclosures noticeably cooler.
• Custom fit: The sail is made to order using D-ring to D-ring measurements so the finished canopy matches the intended installation points.
• Durable construction: Reinforced edges, stainless steel D-rings and double-layer stitching reduce fraying and extend useful life in seasonal conditions.
• Breathable and water permeable: The material sheds heat while allowing air and water to pass through, avoiding ponding after rain.
• Installation flexibility: Can be mounted to trees, roofs, walls or poles and works with standard mounting hardware kits for varied site conditions.

Who It's For

This product suits homeowners, small business owners and hobby farmers who need a large, tailored right triangle shade for patios, seating areas, chicken runs or carports. The custom sizing process and commercial-grade materials make it a good option where off-the-shelf sails do not fit awkward attachment points.

It is less suitable for buyers who expect a pre-cut universal size or those who need a rigid, waterproof canopy; this sail is breathable and designed to reduce heat rather than fully waterproof an area. People wanting the cheapest ready-made square sail should look elsewhere.

Pros & Cons

Pros

• High sun protection from the 200 GSM HDPE fabric blocks most UV exposure.
• Noticeable cooling effect under the sail, often reported as up to 15 degrees cooler.
• Robust hardware and reinforced edges increase longevity in outdoor use.
• Custom sizing ensures a closer fit for irregular spaces compared with standard sails.

Cons

• Customers report the mounted area can appear smaller than expected, so careful measurement is essential.
• Not fully waterproof; it is water permeable by design, so it will not provide total rain protection.

Our Verdict

Frequently Asked Questions

Can this sail be used on trees and poles?
Yes, it is designed for flexible installation and can be attached to trees, roofs, walls or poles using appropriate mounting hardware.

Will the sail stop rain completely?
No, the fabric is water and air permeable, so it reduces sun and heat but will allow some water through rather than acting as a waterproof canopy.

How important are the measurements?
Very important; the sail is made to order from D-ring to D-ring measurements and customers report that incorrect sizing can make the area look smaller than expected.
