ColourTree Custom Size 15ft x 18ft x 23.4ft Beige Right Triangle Sun

In this review the ColourTree custom-size right triangle sun shade sail stands out for anyone who needs a robust, high-coverage shade solution for patios, pools, carports or balconies. The single biggest reason to buy is its 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which delivers strong sun protection and long-term durability compared with recycled materials. The sail is aimed at homeowners and small commercial settings who want a breathable, heavy-duty canopy that blocks sunlight without trapping water.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric resists tearing and fading for longer outdoor life under intense sun exposure.
• UV stabilized compound: Material was laboratory tested and formulated to reduce drying out and deterioration, extending usable life.
• 95% UV blockage: The woven fabric significantly reduces harmful UV and lowers shaded temperatures for safer outdoor use.
• Breathable, water-permeable weave: Allows air and rain to pass through so water does not pool and ventilation is preserved beneath the sail.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings provide secure anchoring and prevent fraying.
• 3 year limited warranty: Coverage under normal weather and use gives added confidence in the product's longevity.

Who It's For

This shade sail is best for homeowners, rental property managers and small businesses needing a heavy-duty, long-lasting triangular canopy that can be custom-sized to fit specific corners and areas. It suits people who prioritise UV protection and durability over ultra-lightweight or decorative fabrics.

Those who should look elsewhere include buyers needing integrated mounting hardware or quick-release systems, since installation kits are sold separately, and anyone who prefers a non-breathable waterproof tarp rather than a permeable shade sail designed to let water pass through.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE gives strong durability and resistance to sun damage.
• Blocks about 95% of harmful UV while remaining breathable to reduce heat below the canopy.
• Well-reinforced seams and stainless steel D-rings make anchoring straightforward and secure.
• Backed by a 3 year limited warranty for normal use and weather.

Cons

• Installation hardware is not included, so additional purchases are required to mount the sail properly.
• Sizing must be chosen carefully for fit; customers noted attention to measurements is important for a true corner fit.
