ShadeMart 7 ft x 19 ft Black Sun Shade Sail UPF50 Rectangle - Cool

In this review of the ShadeMart 7 ft x 19 ft Black Sun Shade Sail, the bottom line is that it is a practical, durable option for homeowners who want significant UV protection and cooler outdoor spaces without a permanent structure. The fabric is woven HDPE and advertised as UPF50, so the main reason to buy is effective sun blocking and breathability that lowers temperatures by a noticeable margin. Installation is straightforward with basic hardware, and the rectangular shape works well for carports, patios and poolside coverage.

Key Features

• MATERIAL: Woven HDPE fabric offers a durable, tear-resistant surface that stands up to sun exposure while remaining lightweight.
• UV PROTECTION: Blocks up to 95% of harmful UV rays so outdoor areas feel cooler and skin exposure is reduced.
• BREATHABILITY: Water permeable and air-permeable fabric lets wind and rain pass through, preventing pooling and reducing strain on attachment points.
• HARDWARE: Stainless steel D rings sewn to heavy duty white webbing provide secure anchor points for typical outdoor mounting kits.
• CUSTOM SIZE OPTIONS: Available in custom sizes so you can order closer to your exact dimensions for patios, pergolas, or carports.
• STYLING: Simple rectangle shape and neutral black color integrate with many exterior palettes and act as a decorative canopy.

Who It's For

This ShadeMart rectangle sun sail is best for homeowners and renters seeking a nonpermanent shade solution for patios, pools, carports or pergolas who value UV protection and airflow. It is also a good pick for people who need a heavy duty fabric that resists wear and can be attached to trees, poles or walls with the correct hardware.

It is less suitable for anyone who needs a fully waterproof cover, as the fabric is intentionally water permeable, or for buyers expecting a factory-perfect geometric rectangle with zero measurement variation; sizes may vary slightly due to manual measurement and trimming.

Pros & Cons

Pros

• High UPF protection that noticeably reduces heat under the sail.
• Durable woven HDPE construction with stainless steel D rings for reliable anchoring.
• Breathable, water-permeable fabric prevents water pooling and reduces wind load.
• Custom sizing available to better match irregular outdoor spaces.

Cons

• Not waterproof, so it will not keep rain completely out.
• Some buyers report variation in the exact rectangle shape or size, so careful measurement is required.
