Custom Size 17ft x 19ft x 25.5ft Red Right Triangle Sun Shade Sail

Our review of this custom-size right triangle shade sail finds it best suited for homeowners and small businesses who need a tailored outdoor cover that blocks strong sun while remaining breathable. The single biggest reason to consider it is the combination of 95% UV protection and a customizable D-ring-to-D-ring fit, which makes it practical for odd-shaped patios, play areas, or outdoor seating where a standard awning will not fit. Installation is straightforward for someone comfortable with basic hardware and measuring, and the 200 GSM HDPE fabric balances strength with airflow.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect skin and reduce sun exposure in covered areas.
• Temperature Reduction: The shade sail can lower surface temperatures by up to 15 degrees compared to unshaded space, making outdoor time more comfortable.
• Custom Fit: Orders are made to the D-ring-to-D-ring measurements so the sail can be tailored to specific shapes and spaces for a neater fit.
• Durable Construction: Reinforced edges, double-layer stitching, and stainless steel D-rings improve longevity and resistance to wear in outdoor conditions.
• Permeable Design: The material is water and air permeable, allowing wind and rain to pass through instead of pooling on the canopy.
• Flexible Installation: The sail can be mounted to trees, walls, roofs or poles and works with common mounting hardware kits when proper clearance is observed.

Who It's For

This shade sail is ideal for homeowners, schools, cafes, and small commercial venues that need a customizable sun shade for an irregular or large area where standard umbrellas or rigid canopies will not fit. It suits people who value UV protection and cooler outdoor spaces while keeping airflow and drainage.

Those who should look elsewhere include buyers seeking a fully waterproof hard canopy or an instant pop-up solution; this product is a permeable fabric sail that requires planning and hardware for installation and occasional maintenance to retain longevity.

Pros & Cons

Pros

• Blocks up to 95% of UV rays for effective sun protection and safer outdoor use.
• Reduces ambient temperature under the sail, improving comfort on hot days.
• Custom measurements mean a tailored fit for irregular spaces and cleaner aesthetics.
• Stainless steel D-rings and reinforced stitching add strength and tear resistance.

Cons

• Durability reports are mixed; while many owners find it long-lasting, at least one report noted degradation after about 14 months in harsh sun.
• Not fully waterproof-its permeable design allows water and air through, which is good for drainage but not for rain protection.

Our Verdict

For anyone needing a tailored outdoor sun solution, this custom right triangle shade sail offers strong value: excellent UV protection, measurable cooling, and durable hardware make it a practical choice for patios, play areas, and commercial seating.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water and air permeable, so it is not fully waterproof but it avoids pooling and sheds most rain through the weave.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each side and provide those dimensions; allow recommended clearance at corners when mounting to posts or walls.

What hardware is included?
The sail features stainless steel D-rings and reinforced edges; typical mounting hardware kits are used but may not be included with every order, so check the product options.
