Custom Size 21ft x 24ft x 31.9ft Blue Right Triangle Sun Shade Sail

In this review the Amgo custom size right triangle shade sail is judged on fit, build and sun protection for backyard and commercial spaces; it is best for buyers who need a large, tailored shade that blocks sunlight while remaining breathable. The single biggest reason to buy is its proven combination of 95% UV blockage and heavy 200 GSM fabric, which delivers reliable sun protection and measurable temperature reduction without trapping heat. For anyone fitting a specific corner or mounting to trees, walls or poles, the made-to-measure D-ring to D-ring sizing is the standout feature.

Key Features

• 95% UV Blockage: The fabric blocks up to 95% of harmful rays, providing safer shade for prolonged outdoor use.
• 200 GSM HDPE Construction: The heavier commercial-grade material increases longevity and resists fraying under sun and wind.
• Temperature Reduction: The sail can lower temperatures by as much as 15 degrees in shaded areas, improving outdoor comfort.
• Custom Fit Measurements: Customers supply D-ring to D-ring dimensions for a tailored fit that works around trees, posts, and structures.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching at the edges improve durability and attachment reliability.
• Breathable & Water Permeable: The weave allows airflow and water permeability so the shaded area does not become stuffy or prone to pooling.

Who It's For

The Amgo custom right triangle shade sail is ideal for homeowners and small businesses that need a large, permanent or semi-permanent shade solution where standard sizes do not fit. It suits patios, playground corners, poolside areas and commercial seating where high UV protection and a cooler microclimate are priorities.

It is less well suited for buyers who want instant off-the-shelf fit without measuring, or for those who need a rigid waterproof canopy; the sail is a breathable, tensioned fabric and requires correct spacing from poles or anchors to perform best.

Pros & Cons

Pros

• High sun protection with 95% UV blockage keeps shaded spaces noticeably cooler.
• Commercial 200 GSM HDPE material with reinforced edges feels sturdy and resists wear.
• Custom sizing from D-ring to D-ring offers a precise fit for irregular spaces.
• Stainless steel D-rings and double stitching give confidence in long-term durability.

Cons

• Some buyers report size expectations differ, so accurate measurement is essential to avoid fit issues.
• Not a rigid, fully waterproof canopy - it is water permeable by design.

Specifications
