ColourTree Custom Size 14ft x 21ft Black Sun Shade Sail Canopy - Heavy

Our review of the ColourTree 14' x 21' black sun shade sail finds it best for homeowners and small businesses that need a durable, high-coverage canopy to cut heat and UV on patios, pools and carports. The single biggest reason to consider this sail is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says has undergone extensive UV testing to improve longevity and resist fading and tearing compared with recycled alternatives. For anyone prioritizing sun protection and breathable coverage, this sail performs as a practical, long-lasting option.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled HDPE fabric provides a stout barrier that resists tearing and is engineered for longer life under sunlight than recycled material.
• UV Stabilized Compound: Fabric treated to resist drying out and fading, helping the canopy retain strength and appearance after prolonged sun exposure.
• 95% UV Blockage: Woven material blocks most harmful UV rays and significantly reduces temperature in shaded areas, useful over patios, pools or carports.
• Breathable Construction: The weave allows air and water to pass through, preventing pooling during rain while keeping the shaded area cooler.
• Reinforced Edges and D-rings: Double layered stitched seams and stainless steel D-rings improve attachment strength and help prevent frayed edges.
• Limited 3 Year Warranty: Coverage under normal weather and use gives added confidence in the product's expected durability.

Who It's For

This shade sail suits homeowners, renters with anchor points, and commercial small-space users who want substantial sun and UV protection without a permanent structure. It is particularly appropriate for patios, balconies, swimming pools and carports where heat reduction and breathable coverage matter.

Those who need a custom installation kit, pole system, or complete all-weather enclosure should look elsewhere or budget for additional hardware, because installation hardware is sold separately and ropes or kits are required for a secure mount.
