Sun Shade Sail 11ft x 22ft Butter Cream Rectangle Canopy - Cool UV

In this review the SUNLAX 11' x 22' butter cream rectangular sun shade sail is evaluated as an affordable, effective way to add lasting shade to a patio, deck, or pergola. The biggest reason to buy is the fabric's high shading rate and UV blockage: the knitted high-density polyethylene blocks up to 95% of UV rays while still allowing cooling breezes through, so it delivers comfortable dappled shade without trapping heat. The sail is practical for DIY installation and is a simple upgrade for outdoor spaces that need sun control rather than full waterproofing.

Key Features

• Premium material: High-density polyethylene offers a 90%-95% shading rate and blocks 95% of UV rays, protecting outdoor seating and skin from direct sun.
• Breathable knit: The permeable mesh allows air circulation and lets light filter through for a cooler, dappled shade instead of a dark enclosed feel.
• Cutting craftsmanship: Finished with double-strength stitched seams and reinforced corners to resist fraying and maintain shape over time.
• Sturdy hardware: Each corner has an anti-rust D-ring and the sail ships with four cords for straightforward attachment to posts or hooks.
• Curved edge design: Curved edges reduce sagging and improve tension for a neater appearance and better shading performance.

Who It's For

This shade sail is well suited to homeowners and renters who want to create a shaded seating area on a patio, deck, or backyard without building permanent structures. It is especially useful where UV protection and airflow are priorities, and for those who prefer a fabric solution that looks cleaner than a freestanding umbrella.

It is not for someone who needs a fully waterproof shelter or precise, guaranteed dimensions; the sail is permeable to rain and the fabric length is measured from D-ring edge to D-ring edge with a tolerance that can vary. Buyers who need custom mounting hardware should budget for separate accessories.

Pros & Cons

Pros

• High shading rate and 95% UV blockage provide reliable sun protection for outdoor living.
• Mesh construction keeps the area cooler by allowing breezes through while offering dappled shade.
• Reinforced seams and anti-rust D-rings increase durability and simplify installation.

Cons

• Not waterproof, so it will not keep furniture dry in heavy rain.
• Size is measured from D-ring to D-ring with a tolerance, so precise fit may require careful planning or custom sizing.

Frequently Asked Questions

Is this shade sail waterproof?
No. The fabric is permeable and allows raindrops through; it provides shade and UV protection but is not a waterproof cover.

Does it come with mounting hardware?
The sail includes 4 cords and has 4 anti-rust D-rings, but mounting hardware such as hooks or turnbuckles must be purchased separately and SUNLAX recommends leaving 0.5-1 ft between fixing points and the sail.

How accurate are the dimensions?
Length is measured from the outer edge of each D-ring to the other and there can be a tolerance up to 4 ft, so measure mounting points carefully or consider custom sizing.
