ShadeMart 13ft x 17ft Blue Rectangle Sun Shade Sail - UPF50 Protection

In this review the ShadeMart 13' x 17' Blue Sun Shade Sail is evaluated for homeowners and small businesses who need effective sun protection and a durable, breathable canopy. The biggest reason to consider this shade sail is its combination of woven HDPE fabric with UPF50 sun blocking that cuts heat and UV exposure while remaining water permeable; installers will appreciate the stainless steel corner D rings and heavy duty webbing for straightforward mounting. This review focuses on real-world use, installation, and durability for patios, carports, and poolside shade.

Key Features

• Material: Woven HDPE fabric provides a strong, tear-resistant surface that still lets air move through to reduce heat buildup.
• UV Protection: Blocks up to 95% of harmful UV rays so shaded areas feel noticeably cooler and protect people and surfaces.
• Water Permeable: The breathable design allows rainwater and airflow to pass through, preventing pooling and reducing wind stress.
• Hardware Ready: Stainless steel corner D rings attached to heavy duty white webbing make attachment to poles, walls, or trees simple and secure.
• Custom Size Options: Multiple custom sizes are available so buyers can match irregular or large spaces when measured carefully.
• Styling: The rectangle shape and blue color integrate into many outdoor decors while doubling as a decorative element.

Who It's For

This shade sail is aimed at homeowners, renters with permission to mount hardware, and small business owners who need a cost-effective way to reduce sun and heat across patios, carports, pergolas, or pool areas. It is particularly useful where airflow and drainage matter, since the water permeable HDPE prevents water pooling and helps keep the shaded area cooler.

People who should look elsewhere include buyers seeking a fully waterproof canopy or those who require a precise factory-cut industrial rectangle without any manual measurement variance. Also, anyone without suitable anchor points or unwilling to install mounting hardware may prefer a freestanding umbrella or rigid canopy instead.

Pros & Cons

Pros

• Durable woven HDPE construction with stainless steel D rings and heavy duty webbing for secure attachment.

• Custom sizing options make it flexible for many outdoor spaces.

Cons

• Not waterproof, so it will not keep a seating area dry during rain.
• Size and rectangle accuracy can vary due to manual measurements, so careful measuring is required.
