ColourTree 17ft x 20ft Green Sun Shade Sail Canopy - Heavy Duty UV

In this review the ColourTree 17ft x 20ft Green Sun Shade Sail Canopy is evaluated as a heavy duty, commercial standard option for outdoor shade. The bottom line: this sail is for homeowners and small businesses who need long-lasting UV protection and airflow; the single biggest reason to buy is its thick 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound that the manufacturer says offers much greater durability under sun exposure. It is not a turnkey kit since hardware is sold separately, but it delivers a substantial, breathable shade surface when installed properly.

Key Features

• 190 GSM Virgin HDPE: The thick 190 GSM, 100% virgin fabric gives a noticeably firmer feel and resists premature drying and tearing compared with recycled alternatives.
• UV Stabilized Compound: The fabric is treated to withstand long sun exposure and is claimed to pass extended laboratory UV testing for improved fade and strength retention.
• 95% UV Blockage: Designed to block up to 95% of harmful UV rays, it significantly reduces direct sun and lowers temperature in shaded areas.
• Breathable Woven Construction: The weave allows air and water to pass through, preventing water pooling and promoting cooling airflow under the sail.
• Reinforced Edges and D-rings: All edges are double layered with reinforced stitching and stainless steel D-rings at corners for secure attachment.
• 3 Year Limited Warranty: The product includes a three year limited warranty under normal weather and use, providing post-purchase protection.

Who It's For

The sail is ideal for homeowners with patios, pools, balconies or carports who want durable sun protection and are prepared to install a fabric-only canopy using separate hardware. Small commercial spaces seeking a heavy duty shade fabric for semi-permanent coverage will also find the thicker 190 GSM material appealing.

This is not aimed at buyers who expect a full installation kit in the box or who want ultra-light or decorative sails; you will need proper shade sail hardware and sturdy anchor points, and nylon rope is discouraged because it can fail under load.

Pros & Cons

Pros

• High fabric quality and thickness provide strong sun resistance and a solid feel.
• Breathable weave reduces heat and prevents water pooling during rain.
• Reinforced seams and stainless steel D-rings improve anchor strength and longevity.
• Three year limited warranty gives added confidence for typical outdoor use.

Cons

• Installation hardware is sold separately, so buyers must plan for additional purchases and correct attachment methods.
• While durability is emphasized, some users report mixed long-term performance in very high winds, so additional anchoring care is advised.
