ColourTree 20ft x 21ft Black Sun Shade Sail Canopy - Heavy Duty UPF50

Our review of the ColourTree 20' x 21' Black Sun Shade Sail finds it best suited for homeowners and small commercial spaces that need a durable, breathable cover for patios, pools, and carports. The single biggest reason to buy is the heavy 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which is engineered to resist fading and drying and to block up to 95% of harmful UV while still allowing air and water to pass through. It feels substantial on installation and offers clear cooling benefits in full sun.

Key Features

• 190 GSM virgin HDPE: A thicker, non-recycled fabric that is designed to be more durable under sun exposure than recycled alternatives.
• UV stabilized compound: The material was lab tested for long-term UV exposure to reduce fading, tearing and drying out.
• 95% UV blockage: The woven fabric reduces UV sunlight and temperature in shaded areas, making it useful for patios, pools and balconies.
• Breathable woven design: Allows air and rainwater to pass through so there is no pooling and the covered area stays ventilated.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings help attachment points hold up under tension when installed properly.
• 3 year limited warranty: Coverage under normal weather and use provides added confidence in the product lifespan.

Who It's For

The ColourTree 20' x 21' sail is ideal for homeowners with a large deck, poolside area, or carport who want significant sun protection and a breathable cover that lowers surface temperatures. It is also a good fit for small commercial outdoor seating areas that need a heavy duty, UV resistant canopy without a rigid structure.

Customers who need a temporary or extremely wind-exposed installation should look elsewhere or pair this sail with heavy-duty hardware and robust anchor points, since some feedback reports material issues in very high wind conditions. Installation hardware is sold separately, so buyers who prefer an all-in-one kit should budget for additional fittings.
