ShadeMart 17 ft x 22 ft Green Sun Shade Sail UPF50 Rectangle - Cool

In this review the ShadeMart 17 ft x 22 ft Green Sun Shade Sail is assessed for homeowners and gardeners who need a large, durable sun screen that reduces heat without trapping moisture. The bottom line: this rectangle HDPE shade sail is best for patios, carports, pergolas and vegetable gardens because it blocks up to 95% of harmful UV rays while remaining water and air permeable, so it lowers temperatures by about 10 to 15 degrees and avoids pooling after rain.

Key Features

• Material: woven HDPE fabric provides a breathable, tear-resistant surface that stands up to sun exposure while allowing airflow.
• UV protection: UPF50 construction blocks up to 95% of harmful UV rays, protecting people and sensitive plants beneath the canopy.
• Hardware: stainless steel D rings attached to heavy duty white webbing give secure attachment points that resist corrosion.
• Water permeability: the fabric is water and air permeable, preventing water pooling and reducing wind load on the structure.
• Custom sizing: the brand offers custom size options so the area of fabric can be matched to a specific patio or carport layout.
• Styling: rectangle shape and color options integrate with landscaping and outdoor furniture to improve aesthetics as well as shade.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners, gardeners, and small business owners who want a large, breathable sun shade for a patio, pool area, pergola or carport. It particularly suits people seeking strong UV protection and lower surface temperatures while maintaining airflow and avoiding water pooling.

Those who need a fully waterproof canopy, or who want an exact factory-cut size without potential manual-measure variance, should look elsewhere; this style is not waterproof and the listed dimensions may vary slightly due to manual measurement.

Pros & Cons

Pros

• Blocks a high percentage of UV rays, providing effective sun protection for people and plants.
• Durable woven HDPE resists tearing and the heavy duty webbing with stainless steel D rings gives reliable anchor points.
• Water permeable fabric prevents pooling and allows breezes to pass, which helps reduce heat beneath the sail.
• Easy to install with proper hardware and adaptable to many attachment points like trees, poles or walls.

Cons

• Not waterproof, so it will not keep rain out of a covered area during storms.
• Color and exact dimensions can vary slightly due to manual measurement and manufacturing tolerances.
