ShadeMart 8 ft x 17 ft Grey Sun Shade Sail UPF50 Rectangle

Our review of the ShadeMart 8 ft x 17 ft Grey Sun Shade Sail finds it best for homeowners and small businesses who need a durable, breathable canopy that significantly reduces sun and heat. The biggest reason to buy is simple: the woven HDPE fabric combines heavy-duty construction with up to UPF50 sun protection, so it cuts sunlight and lowers temperatures while remaining water permeable and long lasting. It is a practical, decorative solution for patios, carports, poolside and pergolas where airflow and UV defense matter most.

Key Features

• Woven HDPE fabric: The high density polyethylene weave provides a tough, tear-resistant surface that stands up to outdoor wear.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays, helping reduce direct sun exposure and lower ambient temperatures.
• Water permeable design: Allows rain and air to pass through so puddling is avoided and airflow is maintained under the canopy.
• Stainless steel D rings and webbing: Heavy duty white webbing with stainless steel corner rings creates secure attachment points for common mounting hardware.
• Custom size options: A wide range of sizes is offered so buyers can match the sail to irregular spaces when measured carefully.
• Rectangle styling: A clean rectangular shape that serves both functional shading and a simple decorative presence in outdoor layouts.

Who It's For

This shade sail suits homeowners, renters with permission to install anchors, and small businesses who need an affordable sun canopy that balances durability and breathability. It is particularly useful for patios, carports, poolside seating, pergolas and yard areas where lowering temperatures and blocking UV is a priority.

Shoppers who need a fully waterproof cover, a perfectly rigid structure, or exact factory-cut precision rectangles may want to look elsewhere; this style is water permeable by design and sizes may vary slightly due to manual measurement and trimming.

Pros & Cons

Pros

• Effective sun protection with UPF50-level blocking that noticeably reduces heat beneath the sail.
• Durable woven HDPE material and stainless steel D rings for long-lasting outdoor use.
• Breathable, water permeable fabric avoids pooling and helps maintain airflow on hot days.
• Custom size availability lets buyers tailor coverage to unusual spaces.

Cons

• Not waterproof, so it will not keep area dry during heavy rain.
• Some customers report size or shape variation, so careful measuring and allowance for manual tolerances is necessary.
