ColourTree 11ft x 11ft x 15.6ft Green Right Triangle Sun Shade Sail

In this review the ColourTree right triangle sun shade sail is assessed for patios, pools and outdoor seating where strong UV protection and durability matter. The bottom line: this bespoke 11' x 11' x 15.6' green canopy is built from a thick 190 GSM virgin HDPE that blocks up to 95% of harmful UV while remaining breathable, so it suits homeowners who want cooler shaded areas without water pooling. It is best for installations using proper hardware and some DIY skill rather than a quick temporary cover.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric gives greater resistance to sunlight and wear compared with typical recycled materials.
• UV stabilized compound: Lab-tested for extended UV exposure so the material resists drying, fading and tearing longer under direct sun.
• 95% UV blockage: The woven fabric significantly reduces temperature and dangerous UV in shaded areas for patios, pools and carports.
• Breathable construction: The weave allows air and water to pass through so rain does not pool and shaded areas stay ventilated.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching around D-rings improve attachment strength and reduce fraying.
• 3 year limited warranty: Manufacturer backing covers normal weather and usage for added peace of mind.

Who It's For

The sail is aimed at homeowners and property managers who want a permanent-looking shade solution that performs in sun exposure: think patios, above-ground pools, balconies and carports where a durable, breathable canopy is needed. Its heavier 190 GSM fabric and UV-stabilized treatment are useful where longevity matters and where the installation will stay up season to season.

It is not ideal for buyers who need a rapid temporary cover or who expect to hang the sail without proper hardware; each D-ring requires cable rope and hardware sold separately, and users who cannot secure solid anchor points should look at simpler umbrella-style options instead.

Pros & Cons

Pros

• High-quality 190 GSM virgin material feels robust and resists sun damage better than recycled alternatives.
• Very good sun protection, with up to 95% UV blockage reducing heat and glare beneath the sail.
• Breathable fabric prevents water pooling and keeps covered areas ventilated after rain.
• Reinforced edges and stainless D-rings add durability and make for secure mount points when paired with proper hardware.

Cons

• Requires separate hardware and correct cable rope for safe installation; poor mounting can lead to premature failure.
• Some customers report mixed durability experiences, so exposure to severe conditions may still cause wear over time.
