ColourTree 12ft x 12ft x 17ft Grey Right Triangle Shade Sail - Heavy

Our review of the ColourTree 12' x 12' x 17' grey right triangle shade sail finds it best suited for homeowners and small businesses who need a durable, breathable canopy for patios, pools or carports. The single biggest reason to buy is the fabric: a 190 GSM 100% virgin HDPE material treated with a UV stabilized compound that passed extensive UV testing, so it resists fading and tearing while blocking significant sunlight. Installation requires separate hardware but once mounted the sail provides reliable shade and airflow.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides long-term durability and resists wear under strong sun exposure.
• UV stabilized compound: Laboratory-tested material resists drying, fading and tearing to extend the life of the sail.
• 95% UV blockage: Blocks most harmful UV rays and reduces ambient temperature in the shaded area for safer outdoor use.
• Breathable woven fabric: Allows water and air to pass through, preventing pooling and reducing wind stress on the canopy.
• Reinforced seams and stainless D-rings: Double layered stitched edges and heavy stitching at corners improve stability and attachment strength.
• Three year limited warranty: Warranty covers normal weather and usage, providing added confidence in the product.

Who It's For

This shade sail is a practical choice for homeowners with patios, balconies, pools or carports who want a heavy duty, long-lasting canopy that blocks most UV and still breathes to avoid water pooling. Small commercial settings that need durable sun protection without frequent replacement will also find the 190 GSM fabric valuable.

It is not ideal for buyers who expect a complete installation kit in the box or who need a different shape or factory-cut hardware included; installation requires separate cables and shade sail hardware and those should be corrosion resistant for best results.

Pros & Cons

Pros

• Very durable 190 GSM virgin HDPE fabric that resists fading and tearing under strong sun.
• Strong UV protection with 95% blockage, reducing heat and sun exposure beneath the sail.
• Breathable weave prevents water pooling and reduces wind load compared with solid covers.
• Reinforced seams and stainless steel D-rings provide secure attachment points.

Cons

• Hardware and cables are sold separately, so additional purchase and correct rope type are required for installation.
• As with most shade sails, performance depends on proper tensioning and mounting points, which may require professional help for complex setups.
