ShadeMart 13 ft x 17 ft Brown Sun Shade Sail UPF50 Rectangle - Cool

Our review of the ShadeMart 13' x 17' Brown Sun Shade Sail finds it best for homeowners and small businesses seeking a durable, breathable shade solution that cuts heat and UV without trapping moisture. The single biggest reason to buy is its woven HDPE fabric with a UPF50 blocking rating that reduces direct sun and can lower temperatures noticeably under the canopy. Installation is straightforward with proper hardware, and the sail doubles as a decorative rectangle canopy for patios, carports, pergolas, and pool areas.

Key Features

• Material: Woven HDPE cloth provides a heavy duty, tear-resistant surface that breathes while blocking sunlight.
• UV Protection: UPF50-rated fabric blocks up to 95% of harmful UV rays, helping reduce surface temperatures beneath the sail.
• Water Permeable: The breathable design allows rain and air to pass through so water does not pool on the canopy and wind loads are reduced.
• Hardware Ready: Stainless steel D rings attached to white heavy duty webbing give secure anchor points for standard shade sail hardware kits.
• Custom Sizing: A range of custom sizes is offered so customers can match their venue measurements for a better fit.
• Styling: Rectangle shape and neutral brown color integrate with many outdoor decors while providing practical shade.

Who It's For

The ShadeMart rectangle sail suits homeowners, landscapers, and small business owners who want a long-lasting, breathable shade that protects from sun and lowers temperature without becoming a rain tarp. It is a solid pick for patios, carports, poolside lounges, and pergolas where airflow and UV protection matter.

Those seeking a fully waterproof canopy or an exact pre-sewn geometric tolerance for precision architectural installs should consider alternatives; the product is explicitly water permeable and manual measurements mean slight variations from perfect rectangle dimensions can occur.

Pros & Cons
