ColourTree Custom Size Right Triangle Shade Sail 12ft x 12ft x 17ft

In this review of the ColourTree 12 ft x 12 ft x 17 ft right triangle shade sail, the bottom line is simple: it is a heavy duty, UV-resistant canopy built for sun protection and long life. The reviewer found it best for homeowners and small commercial spaces seeking a breathable, high-coverage solution that blocks most UV while withstanding harsh sunlight. The single biggest reason to buy is the 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers noticeably better durability and color retention compared with typical recycled alternatives.

Key Features

• 190 GSM Virgin HDPE: Thick non-recycled material gives the sail a sturdier feel and resists tearing under regular sun exposure.
• UV Stabilized Compound: Fabric treated to prevent drying and fading, extending usable life in strong sunlight.
• 95% UV Blockage: Effectively reduces harmful UV and lowers temperature in shaded areas for patios, pools and carports.
• Breathable Woven Fabric: Allows water and air to pass through so there is no pooling during rain and better airflow on hot days.
• Reinforced Edges and D-rings: Double layered stitched seams and stainless steel D-rings give secure attachment points and reduced fraying.
• 3 Year Limited Warranty: Warranty provides extra confidence for normal weather and typical residential use.

Who It's For

The sail is ideal for homeowners with patios, balconies, swimming pools or carports who need a high-coverage shade solution that stands up to prolonged sun. Landscapers or small commercial venues wanting a durable, breathable canopy will appreciate the heavy 190 GSM material and reinforced corners for reliable mounting.

It may be less suitable for buyers who require a full waterproof canopy or those who prefer quick-attach systems with included hardware, since installation hardware is sold separately and the sail is breathable rather than water-impermeable. People looking for ultra-lightweight temporary shades should consider thinner alternatives.
