ColourTree Custom Size 20ft x 21ft x 29ft Black Right Triangle Sun

In this review the ColourTree Custom Size 20' x 21' x 29' black right triangle sun shade sail is evaluated for homeowners and small commercial spaces that need reliable UV protection and long-term durability. The bottom line: this shade sail is aimed at anyone who wants heavy-duty, breathable coverage that blocks up to 95% of UV while resisting fading and tearing, and its chief advantage is the 190 GSM 100% virgin HDPE fabric that laboratory testing showed to be far more durable than recycled alternatives. This review focuses on performance, build quality, and installation realities.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric provides a sturdy canopy surface that resists stretching and delivers a longer service life under sun exposure.
• UV Stabilized Compound: Fabric treated to prevent drying, tearing and fading, which helps maintain appearance and strength after prolonged sun exposure.
• 95% UV Blockage: Blocks most harmful UV rays and reduces heat under the sail, making it practical for patios, pools and carports.
• Breathable Woven Material: The woven design allows air and water to pass through so rain does not pool and ventilation is preserved.
• Reinforced Seams and Stainless D-rings: Double-layer stitched edges and heavy stitching at corners keep the sail from fraying and make mounting more secure.
• Three Year Warranty: A limited 3 year warranty offers extra confidence under normal weather and use.

Who It's For

This sun shade sail suits homeowners, small business owners and installers who need a large, right-triangle canopy with strong UV protection and long-term resistance to sun damage. It is particularly useful over patios, swimming pools, balconies and carports where breathable fabric and reduced heat are priorities.

Customers who require an instant out-of-box mounting kit should look elsewhere, as installation hardware is sold separately and each corner requires a cable rope and appropriate fittings. Those seeking lighter decorative sails or thinner materials intended for infrequent use may prefer less robust, lower GSM options.

Pros & Cons

Cons
