SUNLAX 8' x 12' Outdoor Shade Sail Rectangle — Dark Grey UV-Blocking Breathable Canopy

This SUNLAX 8' x 12' dark grey rectangular shade sail is a high-density polyethylene canopy that blocks up to 95% of UV rays while permitting airflow and light rain to pass through.

Designed for patios, decks, gardens, and play areas, the SUNLAX shade sail combines tightly knitted HDPE fabric with reinforced edges and rust-resistant hardware to deliver durable sun protection without trapping heat. Its breathable mesh construction reduces direct sunlight, helps cool the area beneath, and offers a sleek, modern look that complements outdoor living spaces.

How much sun protection does this shade sail provide?

The fabric is engineered to provide strong UV defense: the dark grey series blocks approximately 90%–95% of sunlight and up to 95% of UV rays. The knit construction disperses harsh light while maintaining visibility and ventilation.

• 90%–95% shading rate for dark grey model
• Blocks about 95% of UV radiation
• Breathable mesh allows cooling airflow
• Not a waterproof barrier—permits light rain through

What makes the SUNLAX sail durable and easy to install?

Manufactured from high-density polyethylene without recycled content, the sail features double-stitched seams and four anti-rust D-rings at the corners. The package includes four cords for mounting, and the curved edges are tailored to reduce sagging and maintain shape over time.

• Double-strength stitched seams resist tearing
• 4 anti-rust D-rings at corners for secure anchoring
• Includes 4 cords for straightforward setup
• Curved edge design helps prevent sag and pooling

How should I measure and mount the 8' x 12' rectangle sail?

Measurement is taken from the outer edge of one D-ring to the outer edge of the opposite D-ring; expect a manufacturing tolerance of ±4 inches. Leave 0.5–1 foot clearance between the sail and each fixing point to allow room for hooks, ropes, or mounting hardware.

• Measure between outer D-ring edges (±4 inches tolerance)
• Recommended 0.5–1 ft gap for mounting hardware
• Mounting accessories sold separately—SUNLAX recommends its own fittings
• Not designed as a waterproof cover—avoid relying on it for heavy rain

Where does this shade sail perform best?

This rectangular canopy works well over seating areas, pergolas, playgrounds, or parking spots where sun reduction and airflow are priorities. The dark grey color reduces glare and adds a contemporary aesthetic without significantly blocking daylight.

• Ideal for patios, decks, and outdoor dining areas
• Good for play zones and poolside shade (not a waterproof roof)
• Helps reduce surface and radiant heat under the sail
• Modern neutral color pairs with many outdoor décors
