11ft x 17ft x 20.2ft Right Triangle Sun Shade Sail - 95% UV Blockage

Our review of this custom right triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need high UV protection in a tailored shape. The single biggest reason to buy is its dependable sun defense: made from 200 GSM HDPE fabric that delivers up to 95% sun protection while still allowing air and water to pass through, so patios, play areas, and animal enclosures stay cooler and ventilated. Installation is flexible enough for trees, walls, or posts when measured D-ring to D-ring for a custom fit.

Key Features

• 200 GSM HDPE fabric: provides durable, long-lasting protection and blocks up to 95% of UV rays for safer outdoor use.
• Temperature reduction: lowers ambient temperature by up to 15 degrees compared with unshaded areas for more comfortable outdoor time.
• Water and air permeable: lets rain and breezes through to prevent pooling and reduce wind stress on the canopy.
• Reinforced hardware: stainless steel D-rings and double-layer stitching improve longevity and resist fraying at attachment points.
• Custom sizing from D-ring to D-ring: allows a precise fit for unusual spaces and options for straight-edge customization if desired.
• Three year assurance: includes a manufacturer's assurance period that covers defects and gives buyer confidence in durability.

Who It's For

This shade sail is ideal for homeowners with patios, decks, backyards, or small commercial spaces seeking a tailored solution rather than a standard square or rectangle. It also works well for users needing a breathable canopy over animal runs or garden areas where ventilation and UV protection matter.

It is not the best choice for someone who wants a very large off-the-shelf sail without custom measuring, or a fully waterproof awning; this model is designed to be water permeable and optimized for shade and airflow rather than complete rain resistance.

Pros & Cons

Pros

• High UV blockage gives excellent daytime protection for people, plants, and animals.
• Breathable HDPE fabric reduces heat below the sail while preventing water pooling.
• Stainless steel D-rings and reinforced edges add durability for seasonal exposure.
• Custom D-ring to D-ring sizing lets buyers get a closer fit for awkward areas.

Cons

• Some customers report sizes run smaller than expected, so careful measurement is required.
• Not fully waterproof, which may be a limitation if you need complete rain coverage.

Specifications
