ShadeMart 7 ft x 17 ft Grey Sun Shade Sail UPF50 Rectangle - Cool

Our review of the ShadeMart 7 ft x 17 ft Grey Sun Shade Sail finds it best for homeowners and small business owners who need a durable, breathable canopy to cut sun and heat without trapping moisture. This rectangle shade sail is made from woven HDPE fabric and blocks up to 95% of harmful UV rays, so the single biggest reason to buy is its combination of reliable sun protection and airflow that helps lower temperatures noticeably in patios, carports, and poolside areas. It is not waterproof, but for many outdoor living spaces that require shade rather than shelter, it delivers dependable performance.

Key Features

• Woven HDPE fabric: The high density polyethylene cloth provides strong, tear-resistant coverage that stands up to regular outdoor exposure.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays so shaded areas stay cooler and occupants get fewer direct sun exposures.
• Water permeable design: The breathable weave allows rain and air to pass through, reducing wind load and preventing pooling.
• Stainless steel corner D rings: Heavy duty rings attached to white webbing give secure attachment points for tie-downs and hardware kits.
• Custom size options: Available in multiple sizes so you can choose the sail that best matches your patio, carport, or pergola measurements.
• Decorative rectangle styling: The clean rectangle shape and neutral grey color integrate with many outdoor designs while providing functional shade.

Who It's For

This shade sail suits homeowners who want a cost-effective way to reduce direct sun on patios, decks, pools, and carports while maintaining airflow. It is also a good choice for renters or small businesses that need a removable, low-maintenance canopy for outdoor seating or display areas.

Those who require full rain protection or a sealed waterproof canopy should look elsewhere, since the fabric is specifically water permeable and designed to breathe rather than shed water. If a perfect rectilinear fit is critical, measure carefully because manual sizing can produce slight variations in shape.
