11ft x 13ft x 17ft Right Triangle Sun Shade Sail - 95% UV Protection

Our review of this custom size right triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need reliable sun protection without a rigid canopy. The single biggest reason to buy is its 95% UV blockage from the 200 GSM HDPE fabric, which provides substantial sun protection while remaining breathable and water permeable. Installation is flexible and the reinforced corners make it robust for routine outdoor use, though careful measuring is required to avoid ordering a sail that is smaller than expected.

Key Features

• 95% UV blockage: The 200 GSM HDPE material blocks up to 95% of harmful UV rays, creating a safer shaded area for people and pets.
• Temperature reduction: The sail can lower perceived temperatures by up to 15 degrees compared with unshaded areas, making patios and play areas noticeably cooler.
• Custom sizing: D-ring to D-ring measurement ordering lets buyers get a tailored fit for irregular spaces or specific mounting points.
• Durable construction: Stainless steel D-rings, reinforced edges, and double-layer stitching reduce fraying and extend the useful life of the canopy.
• Breathable and water permeable: The fabric allows airflow and some water permeability, preventing heat buildup and pooling during light rain.
• 3 year assurance: A three year assurance gives added confidence in the product's commercial-standard build quality.

Who It's For

This shade sail is ideal for homeowners, small business owners, and gardeners who want a durable, breathable shade solution for patios, playgrounds, chicken runs, or seating areas. People who need a custom-fit triangle sail and who can take accurate D-ring to D-ring measurements will get the most satisfaction.

Those looking for a fully waterproof awning, an off-the-shelf exact-size blanket, or who do not want to measure mounting points precisely should consider other products; this sail performs best when ordered to fit and installed with appropriate tension and clearance at each corner.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner and include intended clearance; follow the seller guidance to allow 0.5 ft gap or reduce sides by 1 to 1.5 ft as recommended.

Is the fabric waterproof?
The HDPE fabric is water and air permeable, not fully waterproof; it sheds some water but is designed to allow airflow and avoid pooling.

Can it withstand wind and sun year-round?
With proper installation using the stainless steel D-rings and reinforced edges, it holds up well to sun and routine wind exposure; heavy storms will require taking it down.
