ColourTree Custom Size 11ft x 17ft Waterproof Sun Shade Sail - UPF50

In this review of the ColourTree Custom Size 11' x 17' waterproof sun shade sail, the bottom line is simple: it is built for homeowners and small business owners who need a durable, weather-resistant canopy that blocks sun and rain. The chief reason to buy is the combination of dense 220 GSM virgin polyethylene fabric with a waterproof coating and commercial grade UV treatment, which together deliver reliable shade and wet-weather protection. Installation is straightforward thanks to stainless steel D-rings and reinforced stitching, making this a practical, long-lasting solution for patios, carports and garden shelters.

Key Features

• 220 GSM virgin fabric: The thick non-recycled polyethylene material provides strong tear resistance and a substantial feel that holds shape in wind and tension.
• Waterproof coating: A sealed layer prevents water penetration so the sail sheds rain while still providing continuous shade and protection for outdoor furniture.
• UPF50 sun protection: Commercial grade UV treatment blocks up to 95% of UV rays, keeping underneath areas cooler and protecting surfaces like astroturf from sun damage.
• 316 stainless steel D-rings: Heavy-duty corner hardware eases installation and resists corrosion for coastal or wet climates.
• Double reinforced stitching: All edges are finished with extra stitching to reduce wear at attachment points and extend the life of the sail.
• 3 year limited warranty: The manufacturer offers free replacement within the warranty period if the product does not meet expectations.

Who It's For

This shade sail is ideal for homeowners, renters with permission to anchor a canopy, and small business owners who need an affordable, customizable cover for a patio, carport or seating area. Anyone who prioritizes strong fabric, reliable water resistance and corrosion-resistant hardware will find it a practical choice.

It is less appropriate for those seeking a decorative pergola-style roof or a fully enclosed structure; the sail is a tensioned canopy best suited to open-air shade and rain shedding rather than complete enclosure or heavy snow load applications.

Pros & Cons

Pros

• Sturdy 220 GSM virgin polyethylene fabric delivers a robust feel and long-term durability.
• Waterproof coating and UV treatment keep the area under the sail dry and shaded in most rain and sunny conditions.

Cons

• As a fabric sail, it is not designed for heavy snow loads or as a permanent enclosed roof solution.
• Custom sizing requires careful measurement and planning for proper tension and mounting points.
