ShadeMart 16ft x 17ft Black Rectangle Shade Sail - Breathable UV

In this review of the ShadeMart 16' x 17' Black Rectangle Shade Sail the bottom line is simple: it is a cost-effective, heavy-duty fabric canopy for anyone who needs reliable sun protection without a permanent structure. The reviewer found the woven HDPE material and stainless steel corner D rings make installation straightforward and durable, and the fabric's breathability reduces temperatures noticeably. This review is written from hands-on use and customer feedback to highlight why the sail is best for patios, carports and pool equipment areas where airflow and UV blocking matter most.

Key Features

• Woven HDPE material: The high density polyethylene fabric provides a strong, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel corner D rings: Heavy-duty D rings attached to reinforced white webbing create secure anchor points that stand up to repeated tensioning and outdoor exposure.
• Water permeable design: The sail lets water and air pass through, preventing pooling and allowing cooling airflow even during light rain.
• Temperature reduction: By cutting direct sunlight, the canopy lowers the perceived temperature beneath it by roughly 10 to 15 degrees in typical conditions.
• Custom sizing available: A range of custom sizes helps fit irregular spaces, but accurate measuring is important because dimensions can vary slightly by manual measurement.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners and small business owners who want a flexible, removable shade solution for a patio, carport, pergola or pool equipment area. It suits people who prefer airflow and UV protection over a fully waterproof cover and who may attach the sail to poles, trees or building anchors with a proper hardware kit.

Those who need a fully waterproof canopy, a permanently mounted roof, or exact millimeter-size uniformity should look elsewhere; this sail is designed as a breathable, decorative and functional outdoor fabric rather than a sealed roofing system.

Pros & Cons

Pros

• Durable woven HDPE material and reinforced webbing deliver strong, long-lasting performance and good value for the price.
• Blocks a high percentage of UV rays while remaining breathable, keeping covered areas noticeably cooler.
• Stainless steel D rings provide secure attachment points and simplify installation when used with the right hardware.

Cons

• Not waterproof, so it will not prevent water from passing through during heavy rain.
