ColourTree Custom Size 8ft x 15ft x 17ft Right Triangle Shade Sail

In this review of the ColourTree custom size right triangle shade sail, the bottom line is simple: this is a heavy duty, UV-resistant canopy for anyone who needs reliable sun protection in a custom corner or irregular space. Our review finds the sail best for patios, pools, carports, and balconies where long-term sun exposure and breathability matter most; the standout reason to buy is the 190 GSM 100% virgin HDPE fabric that was lab-tested for extended UV durability.

Key Features

• 190 GSM virgin HDPE fabric: The thick, non-recycled material is designed to resist tearing and fading and outlast lower-grade sails under strong sun.
• UV stabilized compound: Lab testing up to 20,000 hours supports better longevity and reduced drying or brittleness compared to recycled fabrics.
• 95% UV blockage: Blocks most harmful UV rays to lower temperatures and protect shaded areas like patios and pools.
• Breathable woven construction: Allows air and rain to pass through so water does not pool and the sail stays ventilated in storms or hot weather.
• Reinforced seams and stainless hardware points: Double layered stitched edges and D-rings provide stronger attachment points and help prevent fraying and deformation.
• 3-year limited warranty: Coverage under normal use gives extra confidence in the product's durability and workmanship.

Who It's For

This shade sail is ideal for homeowners and small-business owners who need a robust, long-lasting canopy for patios, swimming pools, balconies, carports or courtyard corners where a true 90 or custom triangular fit is required. The durable 190 GSM virgin fabric and UV stabilization suit locations with prolonged sun exposure and occasional wind.

It is not aimed at buyers who expect a full installation kit in the box; hardware and cables are sold separately, so those without mounting points or who prefer turnkey mounts should plan to purchase ColourTree hardware kits or compatible shade sail fittings. Also, if someone needs a completely waterproof tarp rather than a breathable shade fabric, this product is not intended for that use.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE material that feels noticeably thicker and more durable than many recycled alternatives.
• Excellent sun protection with up to 95% UV blockage that reduces heat under the sail.
• Breathable weave prevents water pooling and improves airflow for cooler shaded areas.
• Stitched reinforced edges and stainless steel D-rings make for a secure attachment when paired with proper hardware.

Cons

• Installation hardware is not included and must be purchased separately, which adds cost and requires correct ropes or cables.
• As a fabric shade sail, it is not fully waterproof and will let rain pass through by design.
