ShadeMart 13ft x 20ft Red Sun Shade Sail UPF50 Rectangle - Cool

In this review of the ShadeMart 13' x 20' Red Sun Shade Sail the bottom line is simple: it is for homeowners and small businesses who want an affordable, heavy-duty rectangle canopy that blocks sun and lowers temperature without trapping water. The reviewer found the woven HDPE fabric and stainless steel corner D rings delivered durable, breathable shade that cuts UV and reduces heat by noticeable degrees. Installation is straightforward with the right hardware, and the sail doubles as a decorative addition for patios, carports, pergolas and pool areas.

Key Features

• MATERIAL: Woven HDPE fabric offers a strong, tear-resistant surface that stands up to regular outdoor use while remaining lightweight for easier handling.
• UV PROTECTION: Blocks up to 95% of harmful UV rays, helping to lower temperatures under the canopy and protect people and furnishings from sun damage.
• CORNER FITTINGS: Stainless steel D rings attached to heavy white webbing provide reliable anchor points that resist corrosion in outdoor conditions.
• BREATHABILITY: The water permeable, breathable weave allows water and air to pass through so it does not trap heat or act like a waterproof tarp in storms.
• CUSTOM SIZE OPTIONS: Available in multiple sizes including custom cuts, which makes it easier to fit nonstandard patios or carports when measured accurately.
• STYLING: Rectangle shape and bold red color serve both functional shading and decorative roles to refresh an outdoor space.

Who It's For

This shade sail suits homeowners, renters with outdoor patios, and small business owners who need a cost-effective canopy that offers strong sun protection and improved outdoor comfort. It is especially useful where air flow and drainage are desired because the fabric is designed to be water permeable rather than waterproof.

Those who need a fully waterproof cover, an exact factory-cut geometric rectangle without any size variance, or complex mounting hardware included should look elsewhere or plan to buy a dedicated waterproof awning or a professionally measured installation. Measure carefully before ordering a custom size.
