Right Triangle 8ft x 16ft x 17.9ft Sun Shade Sail - 95% UV Blockage

Our review of this right triangle shade sail finds it ideal for homeowners and light commercial spaces that need reliable sun protection without a permanent structure. The sail's biggest selling point is straightforward: it blocks up to 95% of UV using a heavy 200 GSM HDPE weave while remaining water and air permeable, so it cuts heat and glare without trapping moisture. Installation is flexible enough for yards, patios, and pergola attachments, and the reinforced edges and stainless steel D-rings give confidence that it will last in sun and wind.

Key Features

• 95% UV blockage: High-density 200 GSM fabric delivers strong sunscreen performance for safer outdoor time.
• Temperature reduction: The weave lowers ambient temperature by as much as 15 degrees compared to unshaded areas for a cooler seating area.
• Durable construction: Reinforced edges, double-layer stitching, and stainless steel D-rings resist fraying and provide long-term strength.
• Water and air permeable: The breathable HDPE material sheds some water while allowing airflow to avoid wind loading and pooling.
• Customizable fit: Measured D-ring to D-ring sizing and available straight-edge customization make it straightforward to tailor the sail to irregular spaces.
• 3-year assurance: A three-year assurance backs the product, offering extra peace of mind for outdoor use.

Who It's For

The sail suits homeowners, cafes, and property managers who want a nonpermanent canopy that provides strong sun protection and cooler shade for patios, playgrounds, or dining areas. It works well where trees, posts, or building corners can be used as secure anchor points and where a breathable, water-permeable cover is preferred over waterproof tarps.

Those who need exacting waterproof performance, large continuous coverage without overlaps, or very small incremental size changes may want to consider other shelter types or speak with the seller about custom straight edges and precise measurements prior to ordering.

Frequently Asked Questions

How should I measure for the sail?
Measure from D-ring to D-ring at the planned attachment points and allow the recommended gap near poles or anchors to ensure proper tension.

Is the sail waterproof?
The HDPE fabric is water and air permeable; it sheds some water but is not a fully waterproof membrane.

Can it be left up year-round?
The material is durable and UV resistant, but removing it during extreme storms or prolonged winter exposure will extend its service life.
