ColourTree Custom Size 12ft x 20ft Blue Waterproof Sun Shade Sail

In this review of the ColourTree 12' x 20' waterproof sun shade sail, the bottom line is clear: it is best for homeowners and small businesses who need a heavy-duty, water-resistant canopy that also blocks UV. The reviewer found the sail's standout attribute to be its combination of thick 220 GSM pure virgin polyethylene and a waterproof coating, which together deliver reliable shade, shelter from rain and a cooler surface underneath. Installation is straightforward thanks to stainless steel D-rings and reinforced stitching, making this a practical option for patios, carports and garden seating areas.

Key Features

• 220 GSM pure fabric: The thick virgin polyethylene material provides substantial durability and feels more substantial than typical shade cloth options.
• Waterproof coating: A waterproof layer prevents water penetration so the sail functions as both sun and rain protection for outdoor seating or carport coverage.
• UPF50 protection: Designed to block up to 95% of UV, the sail keeps outdoor areas noticeably cooler and reduces sun exposure for people and surfaces.
• 316 stainless steel D-rings: Premium grade corner D-rings simplify mounting and resist corrosion in outdoor conditions for longer life.
• Double reinforced stitching: All edges are finished with double stitched seams which reduce tearing and distribute tension from mounting points.
• Three year limited warranty: The included warranty and free replacement promise provide added confidence in the product's longevity.

Who It's For

The sail is ideal for homeowners with patios, carports or small yard seating who want a durable, waterproof alternative to a fabric canopy. It suits people who value strong material and secure mounting hardware, and anyone needing a shade solution that also sheds rain.

It is less suitable for those looking for a lightweight, temporary shade for occasional use or for very large commercial installations where custom engineered supports and professional installation would be preferable.
