ColourTree Custom Size 20 ft x 21 ft Brown Sun Shade Sail - Heavy Duty

In this review the ColourTree 20' x 21' brown shade sail is evaluated for homeowners and light commercial users who need a durable, high-coverage canopy that blocks sunlight without trapping heat. The bottom line: this sail is best for patios, pools and carports where long-term UV protection and breathability matter, because it is made from a thick 190 GSM 100% virgin HDPE material treated with a UV stabilized compound that resists fading and tearing over time.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric offers stronger resistance to Sun exposure and is proven in laboratory testing to be more durable than recycled alternatives.
• 95% UV blockage: The woven fabric blocks most harmful UV rays while lowering temperature in shaded areas, making it suitable for patios, pools and balconies.
• Breathable weave: Air and water pass through the material so rain does not pool on the canopy and shaded areas stay ventilated.
• Reinforced construction: Double layered stitched seams and extra heavy corner stitching with stainless steel D-rings help prevent fraying and keep the sail square and secure.
• UV stabilized compound: The fabric is treated to resist drying, tearing and fading, extending usable life under strong sun exposure.
• 3 year limited warranty: The product includes a limited warranty under normal weather and use, providing basic protection for buyers.

Who It's For

This shade sail is a good match for homeowners, small businesses and renters who want an affordable, large-coverage solution to reduce sun and heat over outdoor spaces like patios, swimming pools and carports. The breathable fabric and strong UV protection make it especially useful where airflow and daylight filtering are desired without the bulk of a solid roof.

Those who need an all-in-one mounting solution or prefer pre-attached hardware should look elsewhere, since installation hardware kits are sold separately and proper stainless steel cables or a recommended hardware set are required for best results.
