17ft x 23ft x 28.6ft Black Right Triangle Sun Shade Sail - Heavy Duty

In this review the ColourTree right triangle sun shade sail is evaluated for homeowners and small commercial spaces that need reliable UV protection and durable construction. The standout reason to buy is the heavy 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which the review finds provides strong shade and long-term resistance to fading compared with recycled alternatives. The sail is aimed at patios, pools, carports and balconies where a breathable, 95% UV blocking canopy is desired.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled fabric delivers a noticeably sturdy feel and resists tearing in normal weather.
• UV Stabilized Compound: Laboratory-tested for long-term sun exposure, the material resists drying out and fading to extend useful life.
• 95% UV Blockage: The woven fabric significantly reduces UV sunlight and temperature under the sail for more comfortable outdoor use.
• Breathable Mesh Fabric: Allows air and water to pass through, preventing pooling in rain and improving ventilation compared to solid canopies.
• Reinforced Edges and Hardware: Double layered stitched seams and stainless steel D-rings keep the shape stable and provide secure attachment points.
• 3 Year Limited Warranty: Warranty covers normal weather and usage, offering added confidence in the purchase.

Who It's For

The sail is best for homeowners, landscapers, and small businesses who need a durable, breathable shade solution that blocks most UV while allowing airflow, such as over patios, pool areas, carports or balcony spaces. It suits installations where a right triangle shape fits a true 90 corner or when a triangular aesthetic is preferred.

It is not for buyers expecting a fully waterproof awning or for installations that require included hardware; installation hardware kits are sold separately so those who prefer a turnkey, fully included system should consider other products or plan to buy compatible stainless cables and fixings.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE feels robust and resists UV damage better than recycled fabric.
• Blocks 95% of harmful UV while remaining breathable, reducing heat under the sail.
• Heavy duty reinforced seams and stainless steel D-rings make attachment secure and durable.
• Easy to install for DIY users who purchase appropriate hardware kits separately.

Cons

• Installation hardware is not included and requires separate purchase and correct cable selection for best performance.
• Not fully waterproof; water will pass through by design, which is a benefit for drainage but not for rainproof coverage.

Specifications

Our Verdict

The ColourTree 17' x 23' x 28.6' right triangle shade sail is a solid value for anyone who needs heavy duty UV protection and breathability rather than waterproof coverage. Its 190 GSM virgin HDPE and reinforced construction make it a long-lasting choice for patios, pools and carports, provided buyers plan to purchase suitable hardware separately. For sun control and durability this sail is a practical, cost-effective option.
