ColourTree Custom Size 11ft x 21ft x 23.7ft Green Right Triangle Sun

In this review the ColourTree 11' x 21' x 23.7' green right triangle sun shade sail is evaluated for homeowners and small commercial spaces that need reliable sun protection. The bottom line: it is best for users who want a heavy-duty, breathable shade solution that blocks most UV and holds up better than recycled fabric because it uses 190 GSM 100% virgin HDPE treated with a UV stabilized compound. For many patios, pools, and carports this sail provides cooler shaded space and longer life compared with thinner or recycled alternatives.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric offers stronger tear resistance and durability under prolonged sun exposure compared with recycled alternatives.
• UV stabilized compound: The material was laboratory tested for extended UV exposure to resist drying, fading and premature brittleness for longer outdoor life.
• 95% UV blockage: The woven fabric substantially reduces UV sunlight and lowers temperature in the shaded area, making it useful for patios, pools and balconies.
• Breathable weave: Allows air and water to pass through so rain does not pool and the shaded space remains ventilated.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings provide secure attachment points for proper tensioning.
• 3 year limited warranty: Coverage under normal weather and usage gives added confidence in the product's expected lifespan.

Who It's For

This shade sail suits homeowners and small businesses who need a heavy-duty, long-lasting canopy for patios, above-ground pools, carports and outdoor seating areas. It is a particularly good match for anyone prioritizing UV protection, breathable fabric and a thicker 190 GSM construction built from virgin HDPE.

Those who should look elsewhere include buyers who need a pre-drilled hardware kit included or a very precise pre-measured fit without custom cutting; hardware is sold separately and proper cables and fittings are required for best performance. Also, customers seeking a lightweight temporary cover may find this fabric heavier than ultra-light alternatives.

Pros & Cons

Pros

Cons
