ColourTree Custom Size 4 ft x 9 ft Blue Waterproof Sun Shade Sail

In this review of the ColourTree Custom Size 4 ft x 9 ft Blue Waterproof Sun Shade Sail, the bottom line is simple: this is a dependable, heavy-duty canopy for homeowners who need reliable sun and rain protection. Our review finds the sail best for patios, carports, and yards where a strong, water-resistant fabric and solid attachment points matter most. The standout reason to buy is its robust 220 GSM pure virgin polyethylene construction with a waterproof coating that blocks sunlight and keeps water out, making it an effective all-weather shade solution.

Key Features

• 220 GSM pure fabric: The thick virgin non-recycled polyethylene gives the sail durability and a substantial feel that resists stretching and fading under sun exposure.
• Waterproof coating: The added waterproof layer keeps rain from passing through, so the area beneath stays dry during showers.
• UPF50 sun protection: The fabric blocks 95% of UV rays to protect surfaces and people underneath from harsh sunlight.
• 316 stainless steel D-rings: Premium grade D-rings at each corner provide corrosion resistance and make installation with anchors or ropes straightforward.
• Double reinforced stitching: Finished seams reduce the likelihood of tears and help the D-rings withstand pulling tension over time.
• 3 year limited warranty: A free replacement policy for three years offers added confidence if the product does not meet expectations.

Who It's For

This shade sail is aimed at homeowners and renters who want a durable, weather-resistant canopy for patios, small carports, or garden seating areas. It works well for people who value easy installation and corrosion-resistant fittings, and for those who need both sun blocking and waterproof coverage in one product.

It is less suitable for users who require precise architectural shading for large commercial projects or those who need a freestanding frame included, since the product is a fabric sail intended to be attached to existing structures or posts.

Pros & Cons

Pros

• High-quality 220 GSM virgin polyethylene feels robust and resists wear better than thinner sails.
• Waterproof coating reliably keeps water out, so the sheltered area remains dry in light to moderate rain.
• 316 stainless steel D-rings and reinforced seams simplify mounting and improve long-term durability.
• Three year limited warranty provides peace of mind and a clear replacement path if needed.

Cons

• The sail requires anchor points or hardware not included, so additional fittings or posts may be needed for full installation.
• As with any fabric sail, extremely strong winds or heavy snow loads are not recommended without temporary removal.
