ColourTree Custom Size 11ft x 20ft Rainbow Waterproof Shade Sail

Our review of the ColourTree Custom Size 11' x 20' Rainbow Waterproof Shade Sail finds it best suited for homeowners and small businesses who need a durable, waterproof canopy that blocks sun and rain. The single biggest reason to buy is the heavy 220 GSM pure virgin polyethylene fabric combined with a waterproof coating and commercial UV treatment, which together deliver reliable shade and protection for patios, carports, and play areas.

Key Features

• 220 GSM virgin fabric: Provides a thick, tear-resistant material that stands up to regular outdoor use and helps the sail hold shape under tension.
• Waterproof coating: Keeps water from passing through so the canopy shelters furniture, cars, and ground surfaces during light to moderate rain.
• UPF50 protection: Commercial grade UV resistant treatment reduces sun exposure and helps keep covered areas noticeably cooler.
• 316 stainless steel D-rings: Heavy-duty corner hardware simplifies installation and resists corrosion in outdoor environments.
• Double reinforced stitched seams: Edge finishing and added stitching greatly reduce the risk of tearing at stress points under wind or weight.

Who It's For

This shade sail is ideal for homeowners with patios, carports, balconies, or yards who want a colorful, robust canopy that blocks both sun and rain. It suits gardeners, small cafes, or childcare spaces that need quick-install shelter and prefer a custom-sized option for a tight fit.

It is less appropriate for those seeking a lightweight, temporary beach shade or for large commercial installations where engineered mounting and wind ratings are required; in those cases a structural awning or professional canopy system should be considered.

Pros & Cons

Pros
