Sun Shade Sail 11ft x 22ft Rectangle Canopy - Breathable UV Block

In this review of the SUNLAX Sun Shade Sail 11' x 22' rectangle canopy, the bottom line is simple: anyone who wants effective, breathable UV protection for a patio, deck or pergola will find a lot to like. The sail's standout trait is its dense knitted mesh that blocks up to 95% of UV rays while still allowing cooling breezes and light rain to pass through, creating comfortable, dappled shade rather than a sealed canopy. It is a practical, low-cost way to transform outdoor space without heavy structure work.

Key Features

• High shading rate: The high-density polyethylene fabric delivers a 90%-95% shading rate so direct sun is significantly reduced and surfaces stay cooler.
• UV protection: The material blocks up to 95% of UV rays, helping protect skin and outdoor furniture from sun damage.
• Breathable mesh: The knitted design permits airflow and lets light rain pass through, reducing wind load and pooling compared with solid covers.
• Reinforced edges and hardware: Double strength stitched seams and four anti-rust D-rings at the corners make mounting more secure and durable.
• Curved edge design: The curved edges reduce sagging and improve tension across the sail for better long-term performance and appearance.
• Simple installation kit: The product includes four cords and recommends leaving 0.5-1 ft to allow for mounting hardware or rope for a proper tensioned fit.

Who It's For

The SUNLAX sail suits homeowners and renters who want an affordable shade solution for a backyard, patio, balcony or pergola without building a permanent structure. It is especially useful for those who prefer dappled, ventilated shade over a waterproof cover, and for people who need a lightweight, removable option for summer months.

It is not ideal for someone seeking a fully waterproof awning or for installations where exact edge-to-edge dimensions must be precise; the fabric is measured from D-ring edge to D-ring edge and can have up to a 4 in tolerance, so custom-fit structural projects may require professional sizing or the brand's custom service.

Pros & Cons

Cons

Frequently Asked Questions

Is the shade sail waterproof?
No. The knitted mesh is permeable so it is not waterproof and allows light rain to pass through.

How much space should I leave for mounting?
Leave about 0.5-1 ft between the fixing point and the shade sail to accommodate hardware or rope and ensure proper tension.

Does it include mounting hardware?
The sail includes four cords and anti-rust D-rings; additional hardware such as hooks or turnbuckles should be purchased separately if needed.
