Green Rectangle 19ft x 20ft Sun Shade Sail - 95% UV Protection

Our review of the 19' x 20' green rectangle sun shade sail finds it a practical solution for homeowners and small businesses who need reliable sun protection without blocking airflow. The sail's biggest selling point is its combination of heavy-duty 200 GSM HDPE fabric and up to 95% UV blockage, which translates to noticeably cooler, shaded spaces while still allowing breezes to pass through. Installation is flexible for patios, play areas, or poolside shade, and the included reinforced corners and stainless steel D-rings make it durable enough for frequent use.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect skin and reduce sun exposure in outdoor areas.
• Temperature reduction: The sail can lower ambient temperature by up to 15 degrees compared with unshaded spots, creating a more comfortable outdoor environment.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity and resist fraying under regular use.
• Water and air permeable: The weave lets water and breeze pass through, avoiding puddles and reducing wind stress on the canopy.
• Customizable fit: Made to order from D-ring to D-ring so the sail can be tailored to odd-shaped or specific spaces for a neater installation.
• Easy installation guidance: Clear guidance on corner gaps and mounting points helps achieve proper tension and performance when attaching to trees, walls or poles.

Who It's For

The 19' x 20' green rectangle shade sail suits homeowners with medium to large patios, poolside seating, or play areas who want a breathable canopy that cuts sun and lowers temperature without creating a sealed roof. It also works well for small commercial outdoor seating where airflow and sun protection are both important.

People who need a fully waterproof cover or those who require exact off-the-shelf dimensions without ordering a custom fit might want to consider alternatives; a custom measurement is important to get the promised fit and some buyers reported a size discrepancy in one case.

Pros & Cons

Pros

• High UV protection from 200 GSM HDPE fabric keeps shaded areas significantly cooler and safer.
• Stainless steel D-rings and reinforced, double-stitched edges add durability for extended outdoor use.
• Permeable design prevents water pooling and allows breezes, improving comfort during warm weather.

Cons

• Because items are custom measured D-ring to D-ring, one buyer reported a size mismatch, so careful measurement and communication are required.
• Not a fully waterproof canopy, so it will not replace a solid awning in heavy rain conditions.

Our Verdict

The 19' x 20' green rectangle shade sail delivers solid UV protection and cooler shaded space for patios, pools or outdoor seating at a reasonable value when customized to your measurements.

Frequently Asked Questions

Is this sail waterproof?
Answer. The fabric is water permeable to prevent pooling, so it is not a fully waterproof cover for heavy rain.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring for each side and allow the recommended corner gap; the seller custom-makes the sail to those D-ring measurements.

Will it reduce temperature under the sail?
Answer. Yes, the manufacturer states it can reduce ambient temperature by up to about 15 degrees versus unshaded areas.
