Sun Shade Sail 11 ft x 12 ft Turquoise Blue Rectangle - Cool UV

In this review of the Sun Shade Sail 11 ft x 12 ft Turquoise Blue rectangle canopy, the bottom line is clear: anyone who needs reliable, affordable shade for a patio, deck or pergola should consider it. The single biggest reason to buy is its effective sun blocking and airflow balance - the knitted high-density polyethylene blocks up to 95% of UV while still allowing cooling breezes and light rain to pass through, so it cuts heat without creating a greenhouse effect. The review focuses on real-world use, installation notes, and how it performs in varied weather.

Key Features

• High UV protection: The fabric blocks up to 95% of UV rays, reducing direct sun exposure on patios and seating areas.
• Breathable mesh: The knitted high-density polyethylene lets cooling breezes and raindrops penetrate, keeping the space ventilated and cooler.
• Sturdy construction: Cut from a complete mesh with double strength stitched seams for longer wear and edge integrity.
• Anti-rust hardware: Each corner includes an anti-rust D-ring and the package includes 4 cords for basic installation, simplifying initial setup.
• Curved edge design: Curved edges reduce sagging and improve overall shading performance and appearance.
• Clear sizing guidance: Length is measured between the outer edges of D-rings and a tolerance is noted to help with planning mounting locations.

Who It's For

This shade sail is ideal for homeowners or renters who want a low-cost, effective way to add dappled shade over a patio, pergola, poolside seating area or backyard gathering spot. It suits people who value airflow and cooling as much as UV protection, since the permeable mesh avoids trapping heat.

It is less suitable for buyers who need a fully waterproof canopy or who require rigid structural fittings included with the product, since mounting hardware is sold separately and the fabric is not waterproof. Those looking for a solid rainproof cover or a pre-rigged system should consider other options.

Pros & Cons

Pros

• High shading rate and UV blocking provide effective sun protection for outdoor living areas.
• Breathable material maintains airflow, helping keep covered spaces cooler than solid canopies.
• Durable finishing with double-stitched seams and anti-rust D-rings improves longevity in outdoor conditions.
• Curved edges resist sagging and give a cleaner, more attractive look once installed.

Cons

• Not waterproof, so it will not keep out heavy rain; expect dappled wetting during storms.
• Mounting hardware is not included beyond cords, so additional accessories are needed for secure long-term installation.

Frequently Asked Questions

Is this shade sail waterproof?
The fabric is permeable and not waterproof; it allows light rain to pass through and provides dappled shade rather than full rain protection.

Does it include installation hardware?
The sail includes 4 anti-rust D-rings and 4 cords, but mounting hardware like hooks, turnbuckles or pad eyes must be purchased separately for secure long-term installation.

How much space to leave when mounting?
Leave about 0.5 to 1 ft between the fixing point and the shade sail for mounting hardware, and note size is measured from outer edge of D-ring to outer edge of the opposite D-ring.
