Sun Shade Sail 13ft x 17ft Rectangle Canopy - Cooling UV Block

In this review the SUNLAX 13' x 17' sun shade sail is evaluated as a simple, effective solution for adding dappled shade to patios, decks and pergolas. The biggest reason to consider it is its high shading performance and durable construction: made from high-density polyethylene mesh with a 90%-95% shading rate (80%-85% for white), it blocks up to 95% of UV rays while still allowing cooling breezes and raindrops to pass through. For anyone who wants long-lasting shade without a rigid structure, this sail is a practical, affordable option.

Key Features

• High shading rate: The fabric delivers 90%-95% shading (80%-85% for white) so it noticeably reduces direct sunlight on a deck or patio.
• UV protection: The knitted high-density polyethylene blocks up to 95% of UV rays, helping protect skin and outdoor furnishings.
• Breathable mesh: The permeable design allows air to flow and raindrops to pass, keeping the covered area cooler and preventing puddling.
• Reinforced construction: Seams are double strength stitched and each corner has an anti-rust D-ring for secure attachment and longer life.
• Curved edge design: Curved edges reduce sagging and improve overall tension and appearance once installed.
• Included cords: Four cords are provided to make initial setup easier when combined with separate mounting hardware.

Who It's For

The sail is ideal for homeowners who want a flexible, low-cost shade solution for a patio, backyard deck or pergola and who can provide anchor points for installation. It suits people who prefer breathable coverage that reduces heat without fully blocking airflow.

It is not for someone seeking a fully waterproof canopy or an all-in-one mounting kit, since hardware and permanent fittings must be purchased separately and the sail is not waterproof.

Pros & Cons

Pros

• Excellent sun and UV blocking performance while remaining breathable and cool.
• Sturdy build with double-stitched seams and anti-rust D-rings for durable outdoor use.

• Positive customer feedback on ease of installation and value for money.

Cons

• Not waterproof, so it will not keep rain out of a covered area.
• Mounting hardware is not included, and measurements include D-rings with a tolerance up to 4 ft, requiring careful planning.
