ShadeMart 10 ft x 17 ft Black Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 10 ft x 17 ft Black Sun Shade Sail is judged as a practical, heavy duty option for homeowners and small commercial spaces seeking reliable UV protection without full waterproofing. The biggest reason to consider this sail is its combination of woven HDPE fabric and stainless steel corner D rings, which together deliver durable sun protection and straightforward installation for patios, carports and poolside areas while allowing breathability and water permeability.

Key Features

• Material: Woven HDPE fabric gives the sail a sturdy, fade-resistant surface that blocks up to 95% of harmful UV rays for extended outdoor exposure.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing provide dependable anchor points that resist corrosion and simplify mounting.
• Breathability: The water permeable weave allows water and air to pass through, reducing wind load and preventing pooling while keeping the shaded area cooler.
• Cooling effect: By blocking intense sun, the sail can lower ambient temperatures in the shaded area by roughly 10 to 15 degrees, improving outdoor comfort.
• Custom sizing: A range of custom sizes is available so buyers can match the sail to irregular venues, provided they measure the space accurately before ordering.
• Styling: The rectangle shape and neutral black color integrate easily with many outdoor schemes while acting as a decorative canopy.

Who It's For

The ShadeMart rectangle sail is best for homeowners, renters with permission to attach to existing structures, and small businesses who need strong UV-resistant shade for patios, pergolas, carports, pool areas, or outdoor seating. Its breathable design suits climates where occasional rain is expected and pooling is a concern.

People who need a fully waterproof canopy or strict, measured-precision geometry should look elsewhere; the sail is not waterproof and customers have reported mixed notes on exact shape and final dimensions, so careful measuring and expectation management are important.

Pros & Cons

Pros

• Effective UV blocking and cooling thanks to UPF50-style woven HDPE fabric.
• Durable stainless steel D rings and heavy webbing make attachment secure and long lasting.
• Breathable, water permeable material prevents water pooling and reduces wind stress on anchors.

Cons

• Not waterproof, so it will not provide full rain protection.
• Some customers note size and shape vary slightly due to manual measurements and fabric cut, so exact rectangle precision can be inconsistent.
