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

In this review the ColourTree 11 ft x 20 ft blue waterproof shade sail is evaluated for homeowners and small-business owners who need a durable, weather-resistant canopy. The bottom line is that this sail is best for people who want heavy-duty fabric that blocks sun and rain without complex maintenance; its 220 GSM pure virgin polyethylene and waterproof coating make it a practical alternative to a cloth awning or pergola covering. Installation is straightforward thanks to stainless steel D-rings and reinforced seams, so the product is a solid choice where long-term protection and simple mounting matter.

Key Features

• 220 GSM pure virgin polyethylene: The thick fabric provides a sturdy, long-lasting barrier against sunlight and contributes to the sail feeling substantial rather than flimsy.
• Waterproof coating: A sealed layer prevents water from passing through, letting the sail function effectively as both sun shade and rain shelter.
• 316 stainless steel D-rings: Premium grade D-rings are fitted at each corner to simplify attachment and resist corrosion in outdoor conditions.
• Double reinforced stitched seams: Edge stitching is heavy-duty to reduce tear risk and to hold tension when the sail is mounted taut.
• 3 year limited warranty: The manufacturer backs the sail with free replacement coverage if the buyer is not satisfied within the warranty period.

Who It's For

The ColourTree 11 ft x 20 ft shade sail is ideal for homeowners with patios, small carports, or garden seating areas who need reliable sun protection and occasional rain cover. It suits people who prefer a low-maintenance canopy solution that installs to existing anchors, posts, or trees and who value material thickness and UV resistance.

It is less suited to those requiring decorative, lightweight fabric that drapes for formal events, or buyers who need a custom framing system included; this product provides the sail only, so a separate mounting solution and correct tensioning hardware are necessary for optimal performance.

Pros & Cons

Pros

• High-quality fabric and finish deliver reliable water resistance and sun blocking for outdoor living spaces.
• Stainless steel D-rings and reinforced stitching simplify installation and improve longevity in wet or salty environments.
• The thick 220 GSM material gives a robust feeling and helps keep surfaces underneath cooler in sun.

Cons

• Mounting hardware and structural posts or anchors are not included, so buyers must plan and buy those separately.
• As a heavier material, the sail requires proper tensioning and support to avoid sagging in prolonged wind or heavy rain.
