ColourTree Custom Size 4 ft x 6 ft Blue Waterproof Shade Sail - UPF50

Our review of the ColourTree 4 ft x 6 ft blue shade sail finds it best for homeowners and renters who need a compact, durable cover for a patio, carport, or small yard. The single biggest reason to buy is the combination of a heavy 220 GSM virgin polyethylene fabric with a waterproof coating and commercial UV treatment, which delivers reliable sun and rain protection without the flimsy feel of cheaper sails. Installation is straightforward thanks to stainless steel D-rings and reinforced stitching, making this a practical shelter option for seasonal or year-round outdoor use.

Key Features

• 220 GSM virgin fabric: Thicker, non-recycled polyethylene gives a substantial feel and resists sagging under tension.
• Waterproof coating: The sealed layer prevents water penetration so the sail sheds rain and keeps the area beneath dry.
• Commercial UV treatment: UV resistant finish enhances longevity and maintains color while offering UPF50 sun protection.
• 316 stainless steel D-rings: Premium corner rings simplify secure mounting and resist corrosion in outdoor environments.
• Double reinforced stitching: Hemmed edges and extra stitching reduce the risk of tearing where tension is highest.
• 3 year limited warranty: Free replacement if you are not satisfied, adding confidence to the purchase.

Who It's For

This shade sail is well suited to people who want a compact, robust canopy for a small patio, pergola, carport or above an astroturf play area; its waterproof layer and UV treatment make it useful where both rain and sun are concerns. Do-it-yourselfers who value easy mounting will appreciate the preinstalled stainless D-rings and straightforward shape for most backyard anchor points.

Those who need very large coverage, custom-shaped multi-panel installations, or a decorative luxury fabric should look elsewhere; this product is optimized for practical protection and durability rather than ornate aesthetics or extremely large spans without additional hardware.
