ShadeMart 11 ft x 17 ft Sand Beige Sun Shade Sail - UPF50 Rectangle

Our review of the ShadeMart 11 ft x 17 ft Sand Beige Sun Shade Sail finds it best for homeowners and small-business operators who want a heavy-duty, breathable sun cover that reduces heat and blocks UV without trapping moisture. The single biggest reason to buy is its durable woven HDPE fabric with stainless steel D rings and heavy webbing, which delivers reliable sun protection and long-term outdoor performance while remaining water permeable so rain and wind pass through rather than pooling.

Key Features

• MATERIAL: Woven HDPE fabric provides a robust, tear-resistant surface that stands up to regular outdoor exposure and lasts season to season.
• UV PROTECTION: UPF50 construction blocks up to 95% of harmful UV rays, helping lower temperatures beneath the sail by roughly 10 to 15 degrees for cooler outdoor use.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing offer secure anchor points and resist corrosion in outdoor environments.
• BREATHABILITY: The water permeable design lets rain and air pass through, preventing water pooling and reducing wind uplift compared with solid canopies.
• CUSTOM SIZING: Available in many custom sizes so you can fit nonstandard patios, carports, or pool areas when measured accurately.
• STYLE: Rectangle shape in sand beige blends with many outdoor palettes and provides a neat, architectural shading element.

Who It's For

The ShadeMart rectangle sail is aimed at homeowners, renters with permission to attach anchors, and small businesses that need a sturdy, UV-blocking shade for patios, carports, pergolas, or poolside seating. Its breathable HDPE fabric is especially useful where water runoff and airflow matter, such as over patios or above plants that need ventilation.

Those seeking a fully waterproof canopy, exact factory-precision rectangle cutting, or an all-in-one mounting kit should look elsewhere or purchase mounting hardware separately; the product is sold as the sail fabric with reinforced corners rather than a complete installation kit.
