Custom Size 11ft x 17ft x 20.2ft Blue Right Triangle Sun Shade Sail

In this review the Amgo custom size right triangle shade sail is examined for homeowners and small commercial spaces who need tailored sun protection. The bottom line: it is best for anyone wanting a large, made-to-order shade solution that reliably blocks sun and lowers temperature, because the 200 GSM HDPE fabric promises up to 95% sun protection while remaining breathable and water permeable. Installation flexibility and reinforced hardware mean it performs well where a fixed umbrella or portable canopy falls short.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays so shaded areas stay safer for longer use.
• Temperature reduction: The sail can lower surface temperatures by up to 15 degrees versus unshaded spots, making patios and play areas noticeably cooler.
• Custom sizing: Measurements are taken from D-ring to D-ring for a tailored fit, so awkward or nonstandard spaces can be covered precisely.
• Durable construction: Stainless steel D-rings, reinforced edges, and double-layer stitching improve longevity and resist fraying under tension.
• Breathable and water permeable: The fabric lets air and some water pass through, reducing wind load and pooling while still providing strong sun defense.
• Flexible installation: Can be attached to trees, roofs, walls, or poles and works with common mounting hardware kits for varied mounting options.

Who It's For

This shade sail suits homeowners, restaurants, daycare centers, and small commercial settings needing a large triangular canopy with a custom fit; anyone replacing an umbrella or creating a permanent-seeming outdoor seating area will appreciate the measured D-ring sizing and heavy 200 GSM weave. It is also useful where airflow and water permeability matter, since the sail reduces heat without trapping wind or water.

It is not ideal for buyers who expect a fully waterproof awning or who need a quick temporary shade solution that will be stored and reinstalled often; heavy-duty seasonal use or extremely harsh coastal conditions may affect longevity, so those needing a decades-long product in extreme exposure should consider more industrial-grade fixed roofing.

Pros & Cons

Pros

• High UV blocking performance offers strong sun protection for outdoor seating and play areas.
• Custom D-ring to D-ring sizing delivers a cleaner, tailored installation in irregular spaces.
• Stainless steel hardware and reinforced edges improve build quality and reduce early fraying.
• Breathable, water permeable fabric lowers temperature while avoiding heavy water pooling.

Cons

• Durability is mixed in long-term heavy sun exposure, with some users reporting shorter lifespan under constant UV.
• Not fully waterproof, so it does not replace a solid roof in persistently wet climates.

Frequently Asked Questions

How is the size measured?
Size is measured from D-ring to D-ring, so provide those corner-to-corner dimensions for a precise fit.

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

Is it waterproof?
No, the fabric is water permeable to avoid pooling; it sheds some water but is not a full waterproof replacement for a solid canopy.
