ShadeMart 11ft x 22ft Blue Rectangle Sun Shade Sail - Cool, UV

In this review of the ShadeMart 11' x 22' Blue Sun Shade Sail, the bottom line is simple: this is a practical, cost-effective solution for anyone who needs broad, breathable shade without building permanent structures. The reviewer found it especially useful for patios, carports, and covering pool equipment because the woven HDPE fabric blocks up to 95% of harmful UV rays while remaining water permeable, which prevents pooling and allows airflow. Installation requires basic hardware but the heavy duty stainless steel D rings and reinforced webbing make mounting straightforward for most DIYers.

Key Features

• Material: Woven HDPE fabric provides durable, tear-resistant shade while remaining breathable for air circulation.
• UV protection: Blocks up to 95% of harmful UV rays and noticeably lowers temperatures beneath the canopy.
• Water permeable: Allows rain and moisture to pass through so water does not collect on the surface during storms.
• Attachment points: Stainless steel D rings sewn into heavy duty white webbing give secure, long-lasting anchor points.
• Custom sizing: Multiple custom sizes are available so the sail can be tailored to fit patios, carports, or pools.
• Versatile styling: Rectangle shape and color options make it a decorative addition as well as a functional sun screen.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners and renters who want an affordable, semi-permanent way to add shade over a patio, pergola, carport, or pool equipment. It particularly suits DIY installers who can measure their space accurately and use basic mounting hardware to attach to poles, trees, walls, or roofs.

This sail is not for buyers who need a fully waterproof canopy or a rigid shelter; the fabric is intentionally water permeable and will not block rainfall. Also, customers who want a preassembled frame or a very small, precise shade piece should consider other products.

Pros & Cons

Pros

• High-quality woven HDPE fabric gives strong material strength and resists tearing under normal outdoor use.
• Effective temperature reduction and strong UV blocking improve comfort under the sail.
• Stainless steel D rings and reinforced webbing simplify mounting and increase durability at anchor points.
• Good value compared with building permanent roofing and available in custom sizes for flexible use.

Cons

• Not waterproof, so it will not provide full rain protection or act as a substitute for a roof.
• Accurate measurement and additional hardware are required for a proper installation, which may be a minor hassle for some buyers.
