ColourTree Custom 6 ft x 11 ft x 12.5 ft Right Triangle Sun Shade Sail

Our review of this ColourTree custom right triangle sun shade sail finds it ideal for homeowners and small commercial spaces that need reliable sun protection with a bold color option. The single biggest reason to buy is the thick 190 GSM 100% virgin HDPE fabric, which is UV stabilized after extensive testing and is built to resist fading, tearing and drying out, so it will keep an outdoor area cooler and shaded for seasons. The sail is best when paired with proper hardware and anchored to solid posts, walls or trees.

Key Features

• 190 GSM virgin HDPE fabric: A heavy, non-recycled material designed for durability and tested for extended UV exposure so the sail resists sun damage longer than recycled fabrics.
• 95% UV blockage: The tightly woven fabric blocks most harmful UV rays and helps lower temperatures in covered patios and poolside areas for safer outdoor use.
• Breathable woven construction: Allows water and air to pass through so rain does not pool and the shaded area remains ventilated and comfortable.
• Reinforced edges and hardware-ready corners: Double layered stitched seams and stainless steel D-rings provide secure attachment points and reduce fraying and distortion over time.
• Longer lifespan with UV stabilizer: The material includes a UV stabilized compound to prevent drying and fading, extending useful life under direct sun.

Who It's For

This sail works well for homeowners, pool owners and small commercial properties that need a heavy duty shade solution for patios, balconies, carports and seating areas. It is a good fit when a custom size triangle is required to match a true 90 degree corner or an angled installation.

People who should look elsewhere include those who want a fully waterproof canopy (this is breathable, not waterproof) or buyers without access to sturdy anchor points and who prefer an all-in-one mounting kit, since installation hardware is sold separately.

Pros & Cons
