ColourTree Custom Size 9ft x 12ft x 15ft Right Triangle Sun Shade Sail

In this review the ColourTree custom size right triangle sun shade sail is evaluated for homeowners and light commercial users who need durable, breathable UV protection. The biggest reason to consider it is the thick 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which the reviewer found noticeably more resilient under prolonged sun exposure compared with typical recycled sails. It suits patios, pools, carports and outdoor seating where long-term UV blockage and low maintenance are priorities.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric gives the sail structural strength and resists tearing during regular use.
• UV stabilized compound: Laboratory-tested for extended sun exposure, the treatment helps prevent drying, fading and brittleness over time.
• 95% UV blockage: The woven mesh significantly reduces harmful UV and lowers perceived temperature beneath the sail in summer settings.
• Breathable woven fabric: Air and water can pass through the material so rain does not pool and ventilation remains effective under the shade.
• Reinforced edge construction: Double layered stitched seams and heavy corner stitching around stainless steel D-rings improve attachment strength and resist fraying.
• 3 year limited warranty: The included warranty covers normal weather and usage, providing added confidence for typical outdoor applications.

Who It's For

This sun shade sail is ideal for homeowners, small businesses, and rental property managers who need a robust, long-lasting shade solution that blocks most UV while remaining breathable. It works well over patios, swimming pools, balconies and carports where a right triangle shape fits tight or angled spaces.

It is less suitable for those who need a fully waterproof canopy (the fabric is breathable and allows water through) or buyers who require included hardware; attachment kits are sold separately and proper cable or hardware is recommended for secure installation.

Pros & Cons
