ShadeMart 11ft x 14ft Green Sun Shade Sail Rectangle - Cool

Our review of the ShadeMart 11' x 14' Green Sun Shade Sail finds it best suited for homeowners and small business owners seeking an affordable, effective way to lower outdoor temperatures and add shaded coverage. The single biggest reason to buy is its combination of breathable woven HDPE fabric and sturdy stainless steel corner D rings, which together deliver reliable UV protection and long-lasting attachment points without sealing in heat. Installation is straightforward for anyone comfortable with basic hardware, and the sail works well over patios, carports or pool equipment where airflow matters.

Key Features

• Woven HDPE fabric: blocks up to 95% of harmful UV rays while remaining breathable so heat and moisture do not build up under the sail.
• Stainless steel D rings: provide durable, rust-resistant anchor points that pair with the heavy duty white webbing for secure attachment.
• Water permeable design: allows rain and airflow to pass through, preventing pooling and reducing wind load on the canopy.
• Rectangle shape and multiple colors: fits common outdoor layouts and acts as a decorative element to integrate with existing exterior design.
• Custom size options: available in a range of tailor-made dimensions so you can order a sail that matches your space when measured accurately.

Who It's For

The ShadeMart rectangle shade sail is aimed at people who want cost-effective sun protection for patios, carports, pergolas, or to shield pool equipment; it suits DIY installers who can attach sails to posts, trees, walls or roofs using proper hardware kits. It is also a good option for those who prioritize air circulation, since the breathable fabric lowers temperatures without trapping moisture.

Those who need a fully waterproof canopy, or who expect a rigid, permanent roof replacement, should look elsewhere; this style is explicitly water permeable and not designed to act as a sealed roof. Also, if precise off-the-shelf sizing is critical, measure carefully or choose a custom size to avoid fit issues.

Pros & Cons

Pros

• High UV rejection that can noticeably reduce temperature under the sail.
• Sturdy construction with reinforced webbing and stainless steel D rings for reliable anchoring.
• Breathable, water permeable fabric prevents pooling and allows cooling airflow.
• Good value for the quality compared with building permanent shade structures.

Cons

• Not waterproof, so it will not provide a dry covered space in heavy rain.
• Manual measurement variations mean buyers must be careful when ordering custom sizes.
