ShadeMart 11ft x 17ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 11' x 17' Turquoise Rectangle Sun Shade Sail, the bottom line is simple: it is a practical, heavy-duty shade solution for homeowners who want reliable sun protection and airflow without sealing out moisture. The sail's woven HDPE fabric blocks up to 95% of UV rays and noticeably lowers temperatures, making it a useful choice for patios, carports and poolside areas. The build quality, stainless steel corner D rings and heavy webbing all point to a product designed for repeated outdoor use rather than a decorative one-off.

Key Features

• Material: The woven HDPE fabric resists fading and fraying while remaining breathable so it endures sun exposure without trapping heat.
• UV Protection: Blocks up to 95% of harmful UV rays, which helps reduce surface and air temperatures beneath the sail.
• Hardware: Each corner includes stainless steel D rings attached to heavy-duty white webbing for secure anchor points and improved durability.
• Water Permeable: The fabric allows water and air to pass through, preventing pooling and reducing wind stress compared with solid tarps.
• Custom Size Options: Available in multiple custom sizes so buyers can match the sail to patios, pergolas, carports or pool areas when measured carefully.

Who It's For

The ShadeMart rectangle shade sail is best for homeowners and renters who need practical sun protection over a moderate outdoor area and prefer a breathable canopy that does not collect water. It suits garden seating areas, carports, pergolas and poolside spots where airflow and UV blocking are priorities.

It is less well suited for someone who needs a fully waterproof cover or an exact machine-cut rectangle for precision architectural installs; customers should measure their site carefully and expect some variation from manual sizing while the overall fabric area remains constant.

Pros & Cons

Pros

• High UV protection reduces heat and sun exposure while preserving airflow under the sail.
• Durable construction with stainless steel D rings and heavy webbing for secure attachment points.
• Water permeable design prevents puddling and reduces wind load compared with solid canopies.
• Custom size availability lets buyers fit unusual or large outdoor layouts.

Cons

• Not waterproof, so it will not keep an area dry in heavy rain.
• Some buyers report size or shape variation from manual measurement, so precision installs may need extra planning.
