ShadeMart 9 ft x 17 ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 9' x 17' Turquoise Sun Shade Sail the bottom line is simple: this is a heavy-duty, breathable rectangle shade sail best for homeowners and small businesses who need reliable UV protection and reduced heat without changing drainage. The reviewer found the woven HDPE fabric and stainless steel corner D rings durable and straightforward to install, and the sail noticeably cut sunlight and temperature in outdoor seating areas. It is not waterproof, but it excels where airflow, UV blocking and longevity matter most.

Key Features

• Woven HDPE fabric: The high density polyethylene weave lets air and water pass through while providing long-lasting resistance to sun damage.
• UPF50 sun protection: The sail blocks up to 95% of harmful UV rays, helping lower surface and ambient temperatures under the sail.
• Stainless steel D rings: Reinforced stainless corner D rings attached to heavy white webbing give secure attachment points for standard hardware.
• Water permeable: Because the fabric breathes, rainwater drains through instead of pooling on the surface, reducing stress on attachment points.
• Custom sizing available: ShadeMart offers custom sizes so it can be tailored to irregular patios, carports or pergolas when measured accurately.
• Stylish rectangle shape: The clean rectangular profile and turquoise color make it a decorative addition that integrates with many outdoor designs.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners with patios, pergolas, carports or poolside seating who want strong sun protection and cooler outdoor spaces without sacrificing airflow. It suits people who prefer durable, low-maintenance materials and need a fabric that sheds rain rather than holding it.

It is less suitable for buyers who need a fully waterproof canopy or an exact machine-precision rectangle without any size variation; for those users, a sealed waterproof awning or rigid canopy system would be a better choice.

Pros & Cons

Pros
