ColourTree CTAPRT10 21ft x 21ft x 21ft Grey Triangle Shade Sail

In this review of the ColourTree triangle shade sail, the bottom line is simple: this is a durable, highperformance sun cover for patios, pools and carports where long life and strong UV protection matter. The sail's biggest strength is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the reviewer found delivers consistent shade and longevity compared with thinner recycled sails. For anyone prioritizing robust construction and reliable 95% UV blockage, this shade sail is worth considering.

Key Features

• 190 GSM Virgin HDPE: Thick, nonrecycled fabric gives greater tear resistance and a firmer feel, so the sail holds shape better under tension.
• UV Stabilized Compound: Lab testing to extended hours and the treatment reduce fading and drying, extending the usable life in strong sun.
• 95% UV Blockage: The tightly woven material blocks most harmful UV and noticeably reduces heat and glare in shaded areas.
• Breathable Woven Fabric: Allows air and rainwater to pass through so there is no pooling and the area stays cooler and ventilated.
• Reinforced Edges and Corners: Double layered seams and stainless steel Drings at each corner make installations sturdy and resist fraying over time.
• Three Year Warranty: A limited warranty covers normal weather and usage and reflects the brand's confidence in the materials.

Who It's For

This shade sail suits homeowners and small business operators who need a longlasting sunshade for a patio, balcony, poolside or carport and who value strong UV protection and heavyduty construction. It is especially good where wind and sun exposure are frequent and a thicker, virgin HDPE fabric will perform better than recycled alternatives.

People who want an allinone mounting kit should look elsewhere, since hardware is sold separately and the sail requires proper cables and fittings for secure installation. Those needing an exact offtherack size other than a 21' triangle should also confirm sizing before ordering.
