ShadeMart 11ft x 16ft Red Rectangle Sun Shade Sail - UPF50 Protection

In this review the ShadeMart 11' x 16' red rectangle sun shade sail is assessed for homeowners and small business owners who need a durable, breathable sun screen for patios, carports, and pool areas. The biggest reason to consider it is its combination of woven HDPE fabric and stainless steel corner D rings, which deliver long-lasting UV protection while remaining water permeable. It is a practical choice when lowering temperatures and cutting harsh sunlight are higher priorities than full waterproof coverage.

Key Features

• Material: Woven HDPE fabric provides a strong, tear-resistant canopy that stands up to regular outdoor use.
• UV protection: The sail blocks up to 95% of harmful UV rays, reducing heat and protecting people and outdoor furnishings.
• Breathability: Water permeable design allows rain and air to pass through, preventing pooling and improving comfort under the canopy.
• Hardware: Stainless steel corner D rings attached to heavy duty webbing make anchoring simple and corrosion resistant.
• Custom sizing: Multiple custom size options are available so buyers can match the sail to a specific patio or carport layout.
• Styling: The rectangle shape and bold red color add a decorative element while providing functional shade.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners, renters, and small business owners who need reliable sun protection for a patio, pergola, carport, or pool area and who value breathability over full waterproofing. It is also a good option for people who want corrosion-resistant attachment points for year-round outdoor installation.

Those who need a fully waterproof shelter, an exact factory-cut geometric rectangle for precision architectural use, or an ultra-fine decorative fabric should look elsewhere; this sail is designed for practical outdoor shade and may vary slightly due to manual measurements.
