ShadeMart 16 ft x 17 ft Black Sun Shade Sail - UPF50 Rectangle Canopy

Our review of the ShadeMart 16' x 17' Black Sun Shade Sail finds it best suited for homeowners and small businesses needing a durable, breathable canopy that cuts sunlight and heat without trapping water. The biggest reason to buy is its combination of woven HDPE fabric and stainless steel corner D rings, which deliver lasting sun protection and sturdy attachment points. Installation is straightforward for anyone comfortable with basic mounting hardware, and the sail's water permeable design prevents pooling while blocking up to 95% of harmful UV rays, noticeably cooling covered areas.

Key Features

• Material: Woven HDPE fabric provides a tear-resistant surface that stands up to prolonged sun exposure for reliable shade.
• UV Protection: Blocks up to 95% of harmful UV rays, offering strong sun protection and helping lower temperatures in covered spaces.
• Breathability: Water permeable construction lets rain and air pass through to prevent water pooling and improve comfort under the canopy.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing give secure, corrosion-resistant anchor points for mounting.
• Custom sizing: Available in multiple sizes and colors so customers can choose a rectangle sail that better matches their patio, carport, or pool area.
• Versatility: Can be mounted to poles, trees, walls or roofs with the proper hardware kit for many outdoor applications.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners, renters, and small business owners who want a low-maintenance shade solution for a patio, pergola, carport, or poolside area. It particularly suits users who prioritize UV protection, airflow, and a durable fabric that stands up to sun and wind rather than full waterproofing.

Those who need a fully waterproof canopy, an exact factory-perfect rectangle every time, or an ultra-rigid structure should look elsewhere; this product is water permeable by design and sizes may vary slightly due to manual measurement and fabrication.
