Custom Size 4 ft x 5 ft Rainbow Waterproof Shade Sail - UPF50

In this review of the ColourTree Custom Size 4 ft x 5 ft Rainbow Shade Sail, the bottom line is simple: this canopy is best for homeowners and small-space gardeners who need reliable sun and rain protection in a compact, colorful package. The reviewer found the sail to block UV and moisture effectively while remaining easy to install. The most compelling reason to buy is the combination of a waterproof coating and dense 220 GSM virgin polyethylene fabric that delivers both shade and weather resistance without a bulky frame.

Key Features

• Waterproof coating: The sail sheds rain so outdoor seating and astroturf stay dry and usable during light showers.
• 220 GSM virgin fabric: Thick, non-recycled polyethylene gives a sturdy feel and contributes to long-term durability.
• UPF50 protection: The commercial grade UV treatment significantly reduces sun exposure, keeping shaded surfaces cooler.
• 316 stainless steel D-rings: Heavy-duty corner hardware makes anchoring simple and resists corrosion in outdoor environments.
• Reinforced stitching: Double-stitched edges reduce the chance of tearing and help the D-rings resist pulling tension.
• Three year limited warranty: Free replacement if you are not satisfied, offering extra assurance for outdoor use.

Who It's For

This shade sail suits small patios, balcony gardens, carports, or play areas where a compact, custom-sized rectangle is needed and colorful styling is desired. It works well for people who want a simple, frame-free shelter that blocks both sun and light rain without a permanent structure.

Those who need coverage for large areas, structural wind resistance for exposed locations, or a permanent canopy with tensioning hardware supplied may want to look at larger sails or framed awnings instead. Installers should also plan proper anchor points, as heavy wind conditions require additional rigging beyond the basic corner D-rings.
