ColourTree Custom Size 16ft x 21ft x 26.4ft Right Triangle Sun Shade

Our review of the ColourTree custom size right triangle sun shade sail finds it best suited for homeowners and light commercial users who need reliable UV protection and a durable, breathable canopy. The single biggest reason to buy is the heavy 190 GSM 100% virgin HDPE fabric that passed extended UV testing and is treated with a UV stabilized compound, providing long-lasting color and tear resistance for patios, pools, carports or any outdoor seating area where strong sun exposure is a concern.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material offers superior strength and longevity under prolonged sun exposure compared to recycled alternatives.
• UV stabilized compound: Fabric treatment reduces drying, tearing and fading so the canopy keeps its performance and appearance over time.
• 95% UV blockage: The woven mesh cuts most harmful UV rays and noticeably lowers temperature in shaded areas during peak sun.
• Breathable woven design: Air and water pass through the fabric to prevent pooling and allow cooling breezes without compromising shade.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy corner stitching help keep the sail in shape and make installation hardware attachment secure.
• Three year warranty: Limited warranty provides added confidence for normal weather and usage scenarios.

Who It's For

The sail is ideal for homeowners with patios, pools, balconies and carports who want durable sun protection that breathes and resists fading; landscapers and small businesses that need a long-lasting shade solution will also appreciate the heavy material and reinforced corners. The 95% UV blockage and strong fabric make it a practical choice where sun and heat reduction are priorities.

Those looking for a lightweight, low-cost temporary cover or a waterproof tarpaulin should look elsewhere, since this product is designed as a breathable shade sail rather than a fully waterproof canopy. Installation also requires separate hardware kits and proper attachment points, so DIY buyers without secure mounting points may need professional help.

Pros & Cons

Pros
