ColourTree Custom Size 15ft x 21ft x 25.8ft Red Right Triangle Shade

In this review of the ColourTree custom right triangle shade sail, the bottom line is simple: it is for anyone who needs a heavy duty, long-lasting shade solution for patios, pools, carports or balconies. The standout reason to buy is the durable 190 GSM 100% virgin HDPE fabric that is UV stabilized and lab tested for extended life, delivering reliable UV protection and color retention in harsh sun. Installation requires hardware sold separately, but once mounted it provides breathable, effective shade.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled fabric resists tearing and fading and was lab tested for prolonged sun exposure for improved longevity.
• 95% UV blockage: The woven mesh blocks most harmful UV rays, helping lower surface temperatures and protect people and furniture beneath.
• Breathable, water-permeable weave: Air and rain pass through the fabric, preventing water pooling and reducing wind stress on anchor points.
• Reinforced edges and stainless D-rings: Double layered stitched seams and extra heavy corner stitching increase durability and make mounting more secure.
• Commercial heavy duty build: Designed for regular outdoor use with materials and construction intended for longer service life and low maintenance.
• 3 year limited warranty: Coverage under normal weather and use offers added confidence in the product's expected lifespan.

Who It's For

This shade sail suits homeowners and small businesses that want a strong, permanent-looking fabric shelter that stands up to strong sun and seasonal weather. It is ideal for patios, poolside areas, carports, balconies and other outdoor living spaces where heat and UV are concerns and a bold pop of color is desired.

It is not for buyers who expect hardware to be included or who need a fully temporary, ultra-lightweight canopy; installation requires separate shade sail hardware and strong fixed anchors. Those needing precise DIY sizing guidance should plan for measurement and mounting geometry in advance.

Pros & Cons

Pros
