ColourTree Custom Size Grey Right Triangle Shade Sail 15ft x 20ft x

In this review of the ColourTree Custom Size Right Triangle Shade Sail, the bottom line is simple: this is a heavy-duty, commercial-grade sun shade for people who need reliable UV protection and a robust fabric that breathes. The reviewer found the 190 GSM 100% virgin HDPE material delivers a substantial feel and the claimed 95% UV blockage noticeably reduces heat and glare over patios, pools and carports. It is intended for homeowners and light commercial users who can install a custom-sized sail and want long-lasting sun protection rather than a cheap seasonal cover.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled fabric offers a firmer, more durable canopy surface that resists tearing compared with recycled alternatives.
• UV Stabilized Compound: Laboratory UV testing assures extended life under sun exposure so the fabric resists drying out and fading over time.
• 95% UV Blockage: The woven mesh significantly reduces harmful UV and lowers the perceived temperature in shaded areas.
• Breathable Design: The weave allows air and water to pass so there is no pooling and the shaded area stays ventilated on hot days.
• Reinforced Seams and D-rings: Double layered stitched edges and stainless steel D-rings provide strong anchor points for tensioning and installation.
• Three Year Warranty: A limited 3 year warranty covers issues under normal weather and use, offering added buyer confidence.

Who It's For

This shade sail suits homeowners with patios, balconies, above-ground pools or carports who want a durable canopy that blocks most UV and reduces heat without trapping moisture. It works well for DIY installers who already have anchor points such as poles, trees or walls and who plan to use proper stainless cable and hardware for tensioning.

It is less suitable for buyers who need an off-the-shelf small shade for occasional use or those who cannot install proper mounting hardware; hardware kits are sold separately and poor ropes can lead to failures. If absolute resistance to extreme weather is required without any maintenance, a rigid structure may be a better choice.

Pros & Cons

• Three year limited warranty provides reasonable protection for normal use.
