ColourTree 11ft x 15ft x 18.6ft Black Right Triangle Shade Sail

In this review the ColourTree 11' x 15' x 18.6' black right triangle shade sail is judged as a durable, highcoverage option for homeowners and small businesses that need reliable sun protection. The single biggest reason to buy is the heavy 190 GSM virgin HDPE fabric that resists UV damage and reduces heat under the sail; the review finds it effective at blocking sun while staying breathable and low maintenance for patios, pools, or carports.

Key Features

• 190 GSM virgin HDPE fabric: Provides a thick, heavy duty weave that holds shape and resists tearing for longer outdoor life.
• UV stabilized compound: Treated material survived extended UV testing and reduces fading and brittleness under intense sun exposure.
• 95% UV blockage: Significantly lowers direct UV and temperature in the shaded area so patios and pools feel noticeably cooler.
• Breathable woven construction: Allows air and water to pass through, preventing water pooling and promoting airflow beneath the canopy.
• Reinforced seams and stainless steel Drings: Double layered stitched edges and Drings give secure attachment points for longerterm installations.
• 3 year limited warranty: Covers normal weather and usage so buyers have a reasonable guarantee of durability.

Who It's For

The sail is best for homeowners, cafes, and pool owners who want a heavy duty shade solution that reduces heat and blocks most UV while remaining breathable. It suits installations where a right triangle shape fits a corner space or where one corner needs to reach a taller anchor point.

It is less suitable for users who need a kit with hardware included or those who want a lightweight, lowcost temporary cover; installation requires separate hardware and recommended cabling for a secure mount, so renters or very temporary installs should look elsewhere.

Pros & Cons

Pros

• High quality 100% virgin HDPE gives superior UV resistance and expected longer life than recycled alternatives.
• Blocks up to 95% of harmful UV while remaining breathable to avoid water pooling and improve comfort.
• Sturdy construction with double stitched seams and stainless steel Drings for secure fixings.
• Good value for money given the heavy material weight and three year limited warranty.

Cons

• Installation hardware is sold separately and the sail requires proper cables and anchors for best performance.
• Sizing must be measured carefully for fit; some buyers note sizing accuracy should be checked against the mounting layout.
