Amgo Custom Size 13ft x 21ft x 24.7ft Black Right Triangle Sun Shade

In this review of the custom size right triangle sun shade sail, the bottom line is simple: it is best for homeowners or small commercial spaces that need a tailored, heavy-duty fabric canopy to cut sun and heat. The reviewer found the 200 GSM HDPE fabric and reinforced D-rings deliver dependable everyday protection, while its customization option makes it a good fit for odd-shaped areas. If you need a durable, breathable shade that blocks up to 95% of UV and lowers temperature under the canopy, this shade sail is worth considering.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect skin and reduce sun exposure in the shaded area.
• Temperature reduction: The shade sail can lower ambient temperatures by as much as 15 degrees under the canopy, creating a noticeably cooler spot on hot days.
• Custom sizing: Measured from D-ring to D-ring, the sail is made to order so it can fit unusual layouts like patios, chicken runs, or specific garden areas.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resist fraying in routine outdoor use.
• Breathable and water permeable: The HDPE weave allows air and water to pass through, reducing wind stress and preventing water pooling on the fabric.
• Flexible installation: The sail mounts to trees, walls, poles or roof points and the instructions recommend keeping gaps of 0.5 ft or adjusting by 1 to 1.5 ft per side for tension.

Who It's For

This shade sail is aimed at homeowners, small business owners and hobby farmers who want a sturdy, made-to-measure canopy for patios, play areas, chicken coops or outdoor seating. People who value fabric durability and UV performance will appreciate the stainless steel D-rings and double stitching that come with a 3 year assurance.

It is less suitable for buyers who need a fixed, fully waterproof awning or very large contiguous coverage without seams; because the product is breathable and water permeable, those wanting total rain protection should look for a dedicated waterproof canopy instead.

Pros & Cons

Pros

• Noticeable temperature drop beneath the sail, making shaded areas more comfortable.
• Sturdy build with reinforced edges, double stitching and stainless steel D-rings for long-term use.
• Custom sizing options let you tailor the sail to nonstandard spaces.

Cons

• Some buyers report the finished size can feel smaller than expected, so careful measuring from D-ring to D-ring is essential.
