ColourTree Right Triangle Shade Sail 8ft x 15ft x 17ft - Heavy Duty UV

In this review the ColourTree right triangle shade sail is evaluated for homeowners and light commercial users who need a durable, breathable cover that blocks intense sun. The bottom line: this 8' x 15' x 17' black shade sail stands out for its thick 190 GSM virgin HDPE fabric and lab-proven UV stability, so it is best for patios, pools, carports or any area where long-term sun protection matters. It is a practical choice when durability and real UV blockage are the top priorities.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled material gives noticeably stronger structure and resistance to tearing compared with thinner recycled sails.
• UV stabilized compound: Laboratory UV testing supports longer life and reduced fading, so the sail keeps protection and appearance over seasons.
• 95% UV blockage: The tightly woven fabric cuts most harmful UV, lowering sun exposure and heat under the canopy.
• Breathable woven design: Air and water pass through the fabric to prevent pooling and reduce wind strain on the mounting points.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings improve attachment strength and reduce fraying.
• 3 year limited warranty: Coverage under normal use provides extra peace of mind for installations exposed to sun.

Who It's For

This shade sail is aimed at homeowners, small businesses and property managers who need a heavy duty sunblock for patios, pools, balconies or carports and who value long-term UV resistance. The right triangle shape works well where a corner-to-corner attachment or angled coverage is required, and the 8' x 15' x 17' dimensions suit medium-sized shade layouts.

People who want a fully waterproof canopy, a lightweight temporary tarp, or a preassembled mounting kit included should look elsewhere, since the fabric is breathable rather than waterproof and installation hardware is sold separately.

Pros & Cons

Our Verdict

Frequently Asked Questions

Does this sail block a lot of sunlight?
Yes, the fabric is rated to block about 95% of harmful UV and will noticeably reduce direct sunlight and heat beneath the canopy.

Is mounting hardware included?
No, installation hardware kits and cables are sold separately; stainless steel cables or recommended shade sail kits are advised rather than nylon rope.

Will water pool on the sail?
No, the breathable woven HDPE allows water to pass through, so pooling is unlikely during rain.
