ColourTree 12ft x 17ft x 20.8ft Right Triangle Sun Shade Sail - Heavy

In this review of the ColourTree 12' x 17' x 20.8' right triangle sun shade sail, the bottom line is simple: it is a heavy-duty, commercial-grade canopy for anyone who needs reliable UV protection and long-lasting outdoor coverage. The biggest reason to buy is the thick 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says was lab-tested for durability and stands up to prolonged sun exposure better than recycled material. This review focuses on real-world usability, durability and where the sail makes sense.

Key Features

• 190 GSM virgin HDPE fabric: Provides a thicker, more durable weave that resists tearing and fading compared to recycled alternatives for longer outdoor life.
• UV stabilized compound: The fabric is treated to resist drying out and degradation from sun exposure, helping the sail retain strength over time.
• 95% UV blockage: Blocks most harmful UV rays and reduces temperature in shaded areas, making it useful for patios, pools and carports.
• Breathable woven construction: Allows air and water to pass through, preventing pooling and improving comfort under the sail in warm weather.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners provide secure attachment points for hardware.
• Three year limited warranty: Offers a measure of peace of mind under normal weather and usage.

Who It's For

The ColourTree right triangle shade sail is best for homeowners and small businesses who need a strong, long-lasting sun canopy for patios, balconies, swimming pool areas or carports. Its heavy 190 GSM virgin HDPE fabric and reinforced corners suit installations where durability in strong sun and occasional wind is a priority.

Those who should look elsewhere include buyers seeking an all-in-one kit with installation hardware included, since mounting cables and hardware are sold separately, and people who need a fully waterproof canopy - this sail is breathable and allows water through rather than shedding heavy rain.

Frequently Asked Questions

Does the sail block most UV?
Yes. The woven fabric is rated to block about 95% of harmful UV, reducing sunlight and heat under the canopy.

Is mounting hardware included?
No. Installation hardware kits and cables are required and sold separately; stainless D-rings on the sail need one cable per corner for proper hanging.

Will water pool on the sail?
No. The breathable woven fabric allows water to pass through so pooling is avoided, but it is not a fully waterproof shelter.
