ColourTree Custom Size 12ft x 18ft x 21.6ft Turquoise Right Triangle

In this review of the ColourTree custom size right triangle shade sail, the bottom line is simple: it is for anyone who needs a heavy duty, long-lasting canopy that blocks sunlight effectively. The reviewer found the 190 GSM virgin HDPE fabric and UV stabilized compound to be the single biggest reason to buy, because it resists fading and tearing in continuous sun exposure. For patios, pools, carports or balconies where dependable shade and breathability are priorities, this sail delivers professional-grade protection without complex maintenance.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled material offers superior durability and feels noticeably heavier and more robust than typical sails.
• UV Stabilized Compound: Fabric treated to resist drying, tearing and fading after prolonged sun exposure for extended lifespan.
• 95% UV Blockage: The woven fabric significantly reduces UV penetration and lowers temperature in shaded areas for more comfortable outdoor use.
• Breathable Design: The weave allows air and water to pass through freely so rain does not pool and breeze can cool the shaded area.
• Reinforced Seams and D-rings: Double layered stitched edges and stainless steel D-rings provide secure anchor points and help the sail keep its shape.
• 3 Year Warranty: Limited warranty gives added assurance under normal weather and usage conditions.

Who It's For

This shade sail is best for homeowners and small commercial spaces looking for a durable, high-coverage canopy: patios, pools, carports, balconies and outdoor seating where a right triangle layout fits the site. Installers who value breathable fabric and long-term UV resistance will appreciate the 190 GSM virgin HDPE and reinforced corners.

It is less appropriate for buyers who need a ready-to-install kit out of the box; hardware and cables are sold separately and require proper attachment points. Also, those who want a lightweight, short-term seasonal cover may prefer thinner, less expensive options.

Pros & Cons

Pros

• High material quality and weight provide excellent durability and feel like a commercial-grade product.
• Blocks about 95% of UV, noticeably reducing sun exposure and heat under the canopy.
• Breathable weave prevents water pooling and improves airflow compared with solid tarps.
• Reinforced edges and stainless steel D-rings make installations secure when paired with proper hardware.

Cons

• Installation hardware is not included, so buyers must purchase cables and fittings separately and avoid nylon rope for best results.
• Limited warranty covers three years under normal use, which is good but not indefinite for high-sun regions.
