ShadeMart 11 ft x 17 ft Brown Sun Shade Sail UPF50 Rectangle - Heavy

In this review the ShadeMart 11' x 17' Brown Sun Shade Sail is evaluated as a practical, heavy duty shade solution for patios, carports and yards. The single biggest reason to buy is its combination of durable woven HDPE fabric and UPF50 sun protection that noticeably lowers temperature in outdoor spaces. The sail is not waterproof but is water permeable and breathable, making it a sensible choice for anyone wanting durable UV blockage and airflow rather than a rainproof canopy.

Key Features

• Material: Woven HDPE fabric provides a strong, tear-resistant surface that stands up to regular outdoor exposure.
• UV Protection: Blocks up to 95% of harmful UV rays with a UPF50 level of protection that helps lower ambient temperature under the sail.
• Breathability: Water permeable and breathable construction allows rain and air to pass through, preventing water pooling and heat build-up.
• Hardware Ready: Stainless steel corner D rings attached to heavy duty webbing make the sail ready to hang with appropriate mounting kits.
• Custom Sizing: Available in many sizes and customizable dimensions so buyers can get a sail tailored to their venue when measured accurately.
• Styling: Rectangular shape in multiple colors integrates with outdoor decor while providing functional shade.

Who It's For

The ShadeMart 11' x 17' sail is best for homeowners and renters who need reliable sun protection over patios, pergolas, pools or carports and prefer airflow to a waterproof cover. It suits people who value UV blocking and temperature reduction and who can install the sail on existing anchors such as poles, trees, or building attachments.

It is not the right choice for buyers who need a fully waterproof shelter for frequent heavy rain, or for those who need a perfectly rigid, structural canopy; this product excels at breathable, durable shade rather than complete weatherproofing.

Pros & Cons

Pros

• Durable woven HDPE construction and stainless steel D rings offer long-term resilience in outdoor conditions.
• Effective sun protection, blocking around 95% of UV rays and lowering temperatures beneath the sail.
• Water permeability prevents pooling and increases ventilation, improving comfort on hot days.
• Custom size options and multiple colors allow adaptable styling for many outdoor spaces.

Cons

• Not waterproof, so it will not provide full rain protection for outdoor furniture or occupants.
• Some customers report size or shape variation due to manual measurement, so careful measuring is required before ordering.
