ColourTree Custom 20 ft Triangle Sun Shade Sail - Heavy Duty UV Block

In this review of the ColourTree custom 20 ft triangle sun shade sail, the bottom line is simple: this is a heavy duty, long-lasting shade solution for anyone needing reliable UV protection and a breathable cover for patios, pools or carports. The standout reason to buy is the use of 190 GSM 100% virgin HDPE with UV stabilized compound, which the reviewer found to deliver stronger resistance to sun damage and color fading compared with recycled alternatives while still allowing air and water to pass through.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric offers a noticeably robust feel and resists tearing under regular outdoor exposure.
• UV stabilized compound: Laboratory-tested durability means reduced fading and material breakdown after prolonged sun exposure.
• 95% UV blockage: Provides substantial reduction in harmful UV and lowers temperature in the shaded area for comfort.
• Breathable woven design: Allows air and rainwater to pass through so you do not get pooling after storms and ventilation remains good.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners improve attachment strength and prevent fraying.
• Three year limited warranty: Offers peace of mind under normal weather and use conditions.

Who It's For

The ColourTree shade sail is ideal for homeowners and small commercial users who want a durable, high-UV-blocking canopy for patios, balconies, swimming pools or carports and who plan a semi-permanent installation using proper hardware. The breathable mesh makes it especially suited to locations where ventilation and rain drainage matter.

It may not be the best option for those seeking a cheap short-term cover, nor for installations that require built-in hardware; mounting kits and cables must be purchased separately and the sail assumes attachment points like poles, trees or walls are already in place.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE feels more durable and resists UV damage better than recycled fabrics.
• Blocks up to 95% of harmful UV, noticeably cooling shaded areas in strong sun.
• Breathable weave prevents water pooling and reduces wind stress on the fabric.
• Heavy duty stitched seams and stainless steel D-rings make installation secure when used with proper hardware.

Cons

• Hardware kits and cables are sold separately, so total cost and installation effort are higher than a ready-to-hang unit.
• Sizing accuracy can be important for corner installations; measure carefully before ordering a custom size.
