ShadeMart 13ft x 17ft Red Sun Shade Sail UPF50 Rectangle - Breathable

Our review of the ShadeMart 13' x 17' red rectangle shade sail finds it best suited for homeowners and small businesses seeking a durable, breathable canopy to cut sun and heat without sealing out air. The single biggest reason to consider this shade sail is its combination of woven HDPE fabric and stainless steel corner D rings that deliver long-term sun protection and secure attachment while remaining water permeable so runoff and airflow are preserved.

Key Features

• MATERIAL: Woven HDPE fabric provides a robust, fade-resistant surface that blocks up to 95% of harmful UV rays while staying lightweight enough for easy handling.
• FASTENING: Stainless steel corner D rings attached to heavy duty white webbing create strong, corrosion-resistant anchors that simplify installation and hold up in varied weather.
• BREATHABILITY: The sail is water permeable and breathable so rain passes through and air flows freely, reducing heat buildup beneath the canopy.
• HEAT REDUCTION: By blocking intense sunlight the fabric lowers temperatures beneath the sail, making patios and carports noticeably cooler during peak sun.
• CUSTOM SIZE OPTION: A selection of custom sizes is available so the sail can be matched to specific patios, pergolas, pools or carports when exact dimensions are required.
• STYLING: Rectangle shape in bold red functions as both practical shade and a decorative accent that integrates with many outdoor designs.

Who It's For

This shade sail is ideal for homeowners, renters, and small commercial properties that want a cost-effective way to increase shaded outdoor space without building permanent structures. It works well over patios, carports, pergolas, pools and seating areas where airflow and drainage are desired.

People who need a fully waterproof cover or require a perfectly rigid geometric shape should look elsewhere; the sail is designed to be water permeable and may show small variations from exact rectangle dimensions due to manual measurement and fabric tension when installed.

Pros & Cons

Pros

• High UPF blocking of sunlight keeps shaded areas much cooler and protects skin and furniture.
• Durable woven HDPE resists wear and fading, with stainless steel D rings that stand up to weather.
• Permeable fabric allows rainwater to pass through, preventing pooling and reducing wind load.
• Available in custom sizes to better fit irregular spaces.

Cons

• Not waterproof, so it does not provide full rain protection for items needing dryness beneath.
• Some customers report size and shape can vary slightly from a perfect rectangle due to manual measurements and installation tension.

Our Verdict

The ShadeMart 13' x 17' red rectangle shade sail is a practical, good-value option for anyone who needs reliable UV protection and improved comfort in outdoor spaces without sacrificing airflow or drainage. It is worth buying for patios, carports and poolside areas where breathability and durability matter; those needing total waterproofing or an exact rigid shape should consider alternate solutions.
