ColourTree Custom Size 12ft x 21ft Red Right Triangle Sun Shade Sail

In this review the ColourTree 12ft x 21ft x 24.2ft red right triangle sun shade sail is examined for homeowners and small commercial spaces that need reliable sun protection. The bottom line: this shade sail stands out for its thick 190 GSM 100% virgin HDPE fabric and high UV resistance, making it a smart choice if the main priority is long-lasting, breathable shade that blocks most UV. Installation requires separate hardware, but once fitted it provides sturdy, attractive coverage ideal for patios, pools, or carports.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric is designed to resist tearing and fading and lasts longer under intense sun exposure.
• UV stabilized compound: Laboratory-tested for prolonged UV exposure, the treatment helps prevent drying out and degradation of the material.
• 95% UV blockage: The woven fabric significantly reduces sunlight and heat in shaded areas, improving comfort on hot days.
• Breathable mesh construction: Air and water pass through freely to avoid pooling and allow cooler airflow beneath the sail.
• Reinforced seams and stainless D-rings: Double layered stitched edges and heavy stitching at corners keep shape and provide strong attachment points.
• 3 year limited warranty: Warranty coverage gives added confidence in typical residential and light commercial use.

Who It's For

This shade sail is best for homeowners, pool owners, and small businesses looking for a durable, high-UV-blocking right triangle canopy that withstands strong sun exposure. The heavy 190 GSM virgin material suits locations with intense sunlight where longevity and color retention matter.

It is less suitable for buyers who expect included mounting hardware or who need exact tensioning accessories in the box; installation requires separately purchased hardware and quality cable, and those who want a fully furnished kit should look elsewhere.

Pros & Cons

Pros
