ColourTree Custom Size 18ft x 23ft x 29.2ft Black Right Triangle Sun

Our review of this ColourTree custom right triangle sun shade sail finds it ideal for homeowners and light commercial users who need a durable, high-coverage shade solution. The single biggest reason to buy is its thick 190 GSM virgin HDPE construction treated with a UV stabilized compound, which customers and lab testing both indicate holds up far better under sun exposure than recycled alternatives. It is most useful where long-term sun blockage and breathability are priorities, and it provides straightforward installation when paired with proper hardware.

Key Features

• 190 GSM virgin HDPE: The heavy 190 GSM fabric is made from 100% virgin material for increased strength and longevity compared to recycled alternatives.
• UV stabilized compound: Treated fabric resists drying, tearing and fading so the sail keeps protective performance and appearance longer.
• 95% UV blockage: Blocks most harmful UV rays to significantly reduce temperature and sunlight in shaded areas like patios and pools.
• Breathable woven fabric: Allows air and water to pass through so rain does not pool and shaded spaces remain cooler and ventilated.
• Reinforced edges and hardware: Double layered stitched seams and stainless steel D-rings improve strength at attachment points for reliable mounting.
• Three year warranty: A limited 3 year warranty covers normal weather and usage, giving added purchase confidence.

Who It's For

This sun shade sail is best for homeowners, restaurants with outdoor seating, and poolside areas where a strong, long-lasting fabric is required to block sun and reduce heat. It suits situations that need a large custom right triangle of roughly 18' by 23' by 29.2' and where attachment points such as poles or structural anchors are available.

It is less suitable for buyers who need an off-the-shelf small square or circular canopy or those who want a fully waterproof awning, since the sail is designed to be breathable rather than impermeable. Also plan to buy separate shade sail hardware kits and non-nylon cable for best results.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE fabric that customers report as durable and colorfast in strong sun.
• Excellent UV protection with approximately 95% UV blockage, reducing heat and sun exposure beneath the sail.
• Well finished edges and stainless steel D-rings make mounting secure when used with proper hardware kits.

Cons

• Installation hardware is not included and must be purchased separately; correct cables and fittings are required for optimal performance.
• As a breathable sail it does not provide full waterproofing, so it will not keep heavy rain completely out beneath the canopy.

Frequently Asked Questions

Does the sail include installation hardware?

No, the woven HDPE fabric is breathable to allow water and air through, so it prevents pooling but does not make a fully waterproof canopy.

How durable is the material against sun exposure?
The 190 GSM virgin HDPE has been UV tested and is treated with a UV stabilized compound, offering significantly improved durability and resistance to fading and tearing compared to recycled fabrics.
