ColourTree 20ft x 21ft x 29ft Right Triangle Sun Shade Sail - Heavy

Our review of this ColourTree right triangle sun shade sail finds it best for homeowners and small businesses that need reliable sun protection with a pop of color and a long lifespan. The single biggest reason to buy is the use of 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers noticeably heavier construction and proven UV resistance compared with recycled alternatives. Installation is straightforward for anyone comfortable with basic hardware, and the sail performs well over patios, pools and carports.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material provides a more robust fabric that resists tearing and fading under extended sun exposure.
• UV stabilized compound: Laboratory-tested UV protection reduces degradation and helps the sail maintain strength and appearance over time.
• 95% UV blockage: The woven fabric blocks a large portion of harmful UV and lowers direct sunlight and heat in shaded areas.
• Breathable mesh construction: Allows air and water to pass through, preventing pooling and reducing wind uplift compared with solid tarps.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners improve durability where stress concentrates.
• 3 year limited warranty: Warranty coverage offers added confidence for normal weather and typical residential use.

Who It's For

This shade sail is ideal for homeowners with patios, balconies, pools or carports who want a durable, breathable canopy that blocks most UV. It works well for people who need a custom-sized triangular sail for true 90 degree corners or irregular outdoor layouts and who prefer a long-life fabric rather than thinner recycled options.

It is less suited for buyers who need a fully waterproof canopy or those who expect to leave the sail installed through storms without removing it; the mesh design is breathable rather than waterproof and proper hardware (sold separately) is required for secure mounting.
