ColourTree Custom Size 12ft x 13ft x 17.7ft Right Triangle Shade Sail

In this review of the ColourTree custom size right triangle shade sail, the bottom line is simple: this is a heavy duty, long-lasting sun shade for anyone who needs dependable UV protection and strong construction. The sail is best for homeowners or small commercial spaces wanting a custom fit over patios, pools, carports or balconies; the single biggest reason to buy is the 190 GSM 100% virgin HDPE fabric that is UV stabilized and lab tested for extended outdoor life. The review covers durability, sun blockage, and real installation considerations based on customer feedback.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric provides a firmer weave and greater long-term strength compared to recycled alternatives, which helps resist tearing and fading.
• UV Stabilized Compound: Treated material survived extended laboratory UV testing and is engineered to resist drying out and color loss over time for a longer useful life.
• 95% UV Blockage: Blocks most harmful UV rays and noticeably reduces direct sunlight and heat in shaded areas, making it practical for patios and poolside use.
• Breathable Woven Design: The fabric allows water and air to pass through so rain does not pool and shaded areas remain ventilated and cooler.
• Reinforced Edges and Stainless Steel D-rings: Double-layer stitched seams and heavy-duty corner attachments add strength where the sail endures the most stress during wind and tensioning.

Who It's For

The ColourTree right triangle shade sail suits homeowners, renters with suitable anchor points, and small commercial sites that need a custom-sized canopy for sun protection and temperature reduction. It is particularly appropriate for patios, balconies, pools and carports where a durable, long-lasting fabric and strong corner fittings are important.

People who should look elsewhere include those who need a fully waterproof canopy or an easy all-in-one kit; hardware and cable are sold separately and require proper marine-grade fittings for long-term installations. Also, buyers unwilling to measure carefully should consider a standard-size, ready-made sail to avoid sizing mismatches.

Pros & Cons
