ShadeMart 6 ft x 12 ft Black Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 6 ft x 12 ft Black Rectangle Sun Shade Sail is evaluated for homeowners and small businesses who need reliable sun protection that also breathes. The bottom line: this woven HDPE canopy blocks up to 95% of UV while remaining water permeable, so it lowers heat without pooling water; that makes it a practical choice for patios, carports and poolside shading where airflow and UV protection matter most.

Key Features

• Material: Woven HDPE fabric provides a durable, fade-resistant surface that stands up to regular outdoor exposure.
• UV Protection: Blocks up to 95% of harmful UV rays, helping to reduce surface and air temperatures beneath the sail.
• Breathability: Water permeable and breathable construction allows rain and air to pass through, avoiding water accumulation and improving comfort.
• Hardware: Corner D rings are stainless steel and sewn into heavy duty white webbing for stronger anchor points and longer service life.
• Custom Size: Multiple size options including custom cuts let you match the sail to irregular spaces when measured carefully.
• Styling: Rectangle shape and color options let it serve as both practical shade and a decorative outdoor accent.

Who It's For

This shade sail suits homeowners who need a durable, breathable canopy for a patio, pergola, carport or pool area and who prioritize UV protection and airflow over full waterproofing. It is also a good match for renters or DIYers who want a relatively simple install using existing posts, trees or walls.

Customers seeking a completely waterproof cover or a perfectly rigid structure should look elsewhere; this sail is designed to be flexible, water permeable and to lower temperatures rather than create a dry shelter in heavy rain.

Pros & Cons

Pros

• High UPF performance and woven HDPE construction provide effective sun protection and long-term durability.
• Water permeable design prevents pooling and improves airflow, which helps reduce heat beneath the sail.
• Stainless steel D rings and reinforced webbing create secure attachment points for a strong install.

Cons

• Not waterproof, so it will not keep an area dry during heavy or driving rain.
• Size and shape can vary slightly due to manual measurements, so careful measuring is required before ordering.
