ShadeMart 6 ft x 20 ft Red Sun Shade Sail UPF50 Rectangle - Breathable

In this review the ShadeMart 6 ft x 20 ft Red Sun Shade Sail is presented for homeowners and small businesses who want a straightforward, heavy-duty rectangle canopy that cuts sun and heat without sealing out airflow. The biggest reason to buy is its combination of woven HDPE fabric and stainless steel corner D rings, which give a durable, breathable shade solution that blocks up to 95% of harmful UV while remaining water permeable. For patios, carports, poolside and pergolas this sail balances sun protection and airflow better than a solid tarp.

Key Features

• Woven HDPE fabric: Provides a durable, tear-resistant canopy that resists degradation from sun exposure while allowing air to pass through.
• Stainless steel D rings: Heavy duty corner hardware attached to white webbing gives secure anchor points for a long-lasting installation.
• Water permeable design: Lets rainwater and breeze pass through, reducing wind load and preventing water pooling on the sail.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays and significantly lowers temperatures beneath the sail.
• Custom sizing available: Multiple sizes can be ordered to fit patios, carports, pergolas or other mounting layouts when measured accurately.
• Rectangle styling: A classic shape that integrates with many outdoor designs and can be used as a decorative element as well as functional shade.

Who It's For

The ShadeMart rectangle sail is best for homeowners, rental property managers and small businesses needing a breathable, UV-blocking canopy for patios, carports, pool areas and pergolas. It is particularly useful where airflow matters, such as hot, humid climates or areas prone to wind, because the water permeable fabric prevents puddling and reduces wind stress.

Customers who need a fully waterproof shelter or a perfectly rigid architectural cover should look elsewhere; this sail is intentionally permeable and has some flexibility in final measurements due to manual cutting and fabric behavior.

Pros & Cons

Pros

• Excellent sun protection that can lower temperatures under the sail by noticeable degrees.
• Durable construction with stainless steel D rings and heavy duty webbing for reliable anchoring.
• Breathable, water permeable fabric reduces wind load and avoids pooling during rain.
• Custom size options make it adaptable to many outdoor spaces.

Cons

• Not waterproof, so it will not keep an area dry during heavy rain.
• Some customers report variation in exact shape or size due to manual measurement and cutting.
