ShadeMart 6 ft x 12 ft Grey Sun Shade Sail UPF50 Rectangle - Cool

Our review of the ShadeMart 6 ft x 12 ft Grey Sun Shade Sail finds it best suited for homeowners and small business owners who need a durable, breathable canopy that cuts sun and heat without trapping moisture. Built from woven HDPE with stainless steel corner D rings and heavy duty webbing, this rectangle shade sail delivers reliable sun protection and airflow. It is not waterproof, but it blocks up to 95% of harmful UV rays and noticeably lowers temperatures, making it an effective option for patios, carports, pergolas and poolside shade.

Key Features

• Material: Woven HDPE fabric provides a sturdy, tear-resistant surface that stands up to regular outdoor use.
• UV protection: Blocks up to 95% of harmful UV rays to reduce sun exposure and lower surface temperatures by 10 to 15 degrees.
• Breathability: Water permeable and breathable construction lets air and rain pass through, preventing puddling and wind stress.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing give secure attachment points for a variety of mounting options.
• Custom sizing: Available in multiple sizes and custom dimensions so you can order a sail closer to the exact coverage you need.
• Design: Rectangle shape and multiple color choices make the sail both functional and a straightforward decorative addition to outdoor spaces.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners looking to add effective shade to a patio, carport, pergola or pool area without creating a sealed canopy. It works especially well where airflow and quick drying after rain are important, and for anyone prioritizing UV resistance and durable attachment points for a semi-permanent solution.

It is less suitable for buyers who need a fully waterproof shelter or a precision-cut architectural awning; customers who require strict dimensional accuracy should measure carefully and consider the custom sizing option or a different product purpose-built for waterproof coverage.

Pros & Cons
