ShadeMart 12ft x 17ft Brown Sun Shade Sail Rectangle - UPF50

In this review of the ShadeMart 12' x 17' Brown Sun Shade Sail, the bottom line is clear: this is a durable, breathable shade solution for homeowners who want strong sun protection without trapping heat. It is best for patios, carports and poolside areas where UV blocking and airflow matter most. The sail's woven HDPE fabric and stainless steel D rings give it a robust, long-lasting construction, and the UPF50 rating plus claimed 95% UV blockage are the single biggest reasons to consider it for cooling outdoor living spaces.

Key Features

• Material: Woven HDPE fabric provides a heavy-duty, tear-resistant canopy that stands up to regular outdoor exposure.
• UV Protection: Blocks up to 95% of harmful UV rays and carries a UPF50 level of sun protection to significantly reduce direct sunlight exposure.
• Breathability: Water permeable and breathable construction lets water and air pass through, reducing heat buildup beneath the sail.
• Hardware: Stainless steel corner D rings attached to white webbing offer secure anchor points for a stable installation.
• Custom sizing: Multiple custom sizes are available so you can choose a sail that fits a patio, carport, pergola or pool area when measured accurately.
• Style: Rectangle shape and neutral brown color blend with many outdoor decors while also providing functional shade.

Who It's For

The ShadeMart rectangle shade sail is aimed at homeowners and renters who want a breathable, effective sun screen for patios, pergolas, carports and pool edges, especially where lowering ambient temperature is important. It suits DIY installers who can source or already have compatible hardware kits and strong anchor points such as posts, walls or trees.

Those looking for a fully waterproof canopy should look elsewhere, since the sail is explicitly water permeable. Buyers who require a precisely geometric rectangle for a finished architectural look should also measure expectations carefully, as manual production can lead to slight shape variation.

Pros & Cons

Pros

• High UV protection and UPF50-level shading significantly reduce sun exposure and lower temperatures.
• Durable woven HDPE fabric and stainless steel D rings withstand heavy use and harsh conditions.
