ColourTree Right Triangle Sun Shade Sail 17ft x 21ft x 27ft - Heavy

In this review the ColourTree right triangle sun shade sail is evaluated for homeowners and small businesses who need reliable sun protection without a permanent structure. The bottom line: this shade sail stands out because of its thick 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers long-lasting UV protection and strong resistance to fading and tearing. For anyone wanting a breathable, durable canopy that blocks most UV while allowing airflow, this product is a practical, heavy duty option for patios, pools and carports.

Key Features

• 190 GSM virgin HDPE fabric: The thick, non-recycled material offers noticeably greater durability under sun exposure compared with recycled alternatives.
• UV stabilized compound: Laboratory testing to simulate extended sun exposure reduces fading and drying, extending the usable life of the sail.
• 95% UV blockage: The woven fabric significantly lowers harmful UV and sunlight in shaded areas, making outdoor spaces cooler and safer.
• Breathable woven construction: Air and water pass through the mesh so there is no pooling after rain and the shaded area remains ventilated.
• Reinforced edges and stainless steel D-rings: Double layered stitched seams and heavy corner stitching help prevent fraying and secure attachment points.
• 3 year limited warranty: Provides reasonable coverage under normal weather and usage for peace of mind.

Who It's For

The sail is best for homeowners, pool owners, and small commercial spaces that need a robust, temporary shade solution without building structures. It suits people who want high UV protection and long-term color retention, especially in sunny climates where sun damage is a concern.

It is not for buyers who need a waterproof canopy or an instant mounting kit; installation hardware is sold separately and hardwearing cables or hardware are recommended. Those seeking a lightweight, decorative-only fabric might prefer a thinner, less durable option.
