ColourTree Custom Size 9 ft x 18 ft Brown Waterproof Shade Sail

In this review of the ColourTree Custom Size 9 ft x 18 ft Brown Waterproof Shade Sail, the bottom line is simple: this is a heavy-duty, weather-resistant canopy for homeowners who need reliable shade and rain protection. The reviewer found the sail to be well made from thick 220 GSM virgin polyethylene with a waterproof coating and reinforced edges, so it blocks sun and keeps water out. If you want a sturdy patio or carport shelter that is straightforward to install and backed by a three year limited warranty, this sail delivers the essentials without gimmicks.

Key Features

• 220 GSM virgin polyethylene: The thick non-recycled fabric provides substantial weight and durability compared with lighter sails, helping it hold shape under tension.
• Waterproof coating: The added waterproof layer keeps rain from passing through, so covered areas stay dry during showers.
• 316 stainless steel D-rings: Premium grade D-rings at each corner make it easier to anchor the sail securely to posts or wall mounts.
• Double reinforced stitching: All edges are double stitched to reduce tearing and to distribute pulling tension from attachments.
• UPF50 sun protection: The fabric blocks a high percentage of UV, helping to keep surfaces and people shaded and protected from sun exposure.

Who It's For

This shade sail is best for homeowners and renters who need a robust, rectangular canopy for a patio, carport, yard or over outdoor furniture. It suits anyone who values water resistance and fabric thickness over the ultra-lightweight, temporary sails sold for fair-weather use.

People who want a perfectly tailored fit should note that this listing is a custom size product, so measure installation points carefully. If you need a floating, highly breathable shade that prioritizes airflow over waterproofing, a mesh sail may be a better choice.

Pros & Cons

Pros

• Very good fabric quality that customers describe as thick and durable, so the sail holds tension and lasts longer.
• Effective water resistance; several users report no water penetration and dry coverage under rain.
• Easy to install thanks to stainless steel D-rings and reinforced edges that take hardware well.
• Attractive color options that maintain appearance while providing strong shade and UV blocking.

Cons

• Because the material is waterproof and heavier, it is less breathable than mesh shade sails and can retain some heat beneath in very hot conditions.
• Custom sizing requires careful measurement; improper fit can cause installation challenges or extra hardware needs.
