Custom Size 17 ft Triangle Sun Shade Sail - UPF50+ 95% UV Blockage

Our review of this custom size triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need dependable sun protection and a tailored fit. The biggest reason to buy is the combination of heavy-duty 200 GSM HDPE fabric and customizable sizing that delivers 95% UV blockage and a measurable cooling effect without sealing out air or water. Installation is flexible and straightforward, and the reinforced hardware and stitching promise durability for patios, play areas, or animal enclosures.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, making it a reliable sun-screening solution for outdoor living spaces.
• Temperature reduction: The fabric reduces ambient temperature by up to 15 degrees compared with unshaded areas, creating cooler, more comfortable zones.
• Customizable fit: Measured D-ring to D-ring so the sail is made to fit your exact dimensions and can be ordered to match odd spaces.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity in sun and wind exposure.
• Permeable design: Water and air permeable mesh lets heat and moisture escape so the area below stays airy and avoids pooling water.
• Installation flexibility: Can be attached to trees, roofs, walls or poles and adjusted with recommended clearances for optimal tension.

Who It's For

This shade sail is for anyone needing a custom triangular canopy for patios, decks, gardens, playgrounds, or small commercial outdoor seating areas who values sun protection and ventilation. It also works well for people who want a tailored fit rather than off-the-shelf sizes and who need a product that tolerates summer heat and wind.

Those who should look elsewhere include buyers seeking a fully waterproof awning or a rigid structure; this sail is water and air permeable and is designed to provide shade and cooling rather than full rain protection. Also, customers expecting a very large single-piece canopy without precise measurement should consider alternative solutions.

Pros & Cons

Pros

• High sun protection with up to 95% UV blockage from durable 200 GSM HDPE material.
• Reduces temperatures by as much as 15 degrees, improving outdoor comfort.
• Stainless steel D-rings and reinforced stitching offer commercial-standard durability.
• Custom sizing ensures a neat fit for irregular or specific installation points.

Cons

• Not fully waterproof since the fabric is water permeable, so it will not prevent all rain from coming through.
• Customers noted size can be surprisingly small if measurements are not taken carefully, so precise D-ring to D-ring measurement is essential.

Our Verdict

Frequently Asked Questions

Is this sail waterproof?
Answer. No, the fabric is water and air permeable so it will not completely block heavy rain, but it prevents direct sun and allows water to pass through.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring for each side and leave the recommended clearance between D-rings and attachment points; the sail is made to those precise measurements.

Will it hold up in wind and sun?
Answer. Yes, stainless steel D-rings, reinforced edges and double-layer stitching improve durability in sun and wind, though proper tensioning and secure attachment are important.
