ColourTree Custom Size Green Right Triangle Shade Sail 13ft x 17ft x

In this review of the ColourTree Custom Size Green Right Triangle Shade Sail, the bottom line is simple: this is for anyone who needs a heavy duty, breathable sun canopy that prioritizes UV protection and long-term outdoor use. The reviewer found the thick 190 GSM virgin HDPE fabric and UV stabilized compound to be the defining strengths, offering substantial cooling and durability for patios, pools and carports while remaining easy to install when paired with proper hardware.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric provides a dense, sturdy weave that resists tearing and holds shape under tension.
• UV stabilized compound: Laboratory UV testing and treatment help prevent fading and drying, aiming to extend usable life in direct sun.
• 95% UV blockage: The woven mesh blocks most harmful rays and noticeably reduces temperature under the canopy for daytime use.
• Breathable, water-draining weave: Air and rain pass through the fabric so water does not pool and the shaded area remains ventilated.
• Reinforced edges and D-rings: Double-layer stitched seams and stainless steel D-rings at corners improve mounting strength when attached correctly.
• 3 year limited warranty: The product includes a limited warranty under normal weather and usage for additional buyer confidence.

Who It's For

This shade sail is best suited for homeowners with patios, above-ground pools, balconies, carports or small commercial outdoor seating areas who want a durable, high-UV-blocking canopy. It is particularly useful where a breathable fabric is needed to avoid water pooling and to maintain airflow while reducing heat and sun exposure.

People who should look elsewhere are those needing a lighter, cheaper temporary cover or a fully waterproof tarp; this is a breathable shade fabric rather than a waterproof shelter. Also, buyers must plan for separate hardware, as mounting kits and appropriate cables are required but sold separately.
