ShadeMart 9 ft x 17 ft Green Sun Shade Sail UPF50 - Durable Outdoor

In this review of the ShadeMart 9 ft x 17 ft Green Sun Shade Sail, the bottom line is simple: this is a heavy-duty, breathable rectangle canopy for homeowners and small businesses who want reliable sun protection without trapping heat. Designed from woven HDPE with stainless steel D rings and heavy webbing, the sail blocks most UV while allowing water and air to pass through, making it a practical choice for patios, carports, pools and pergolas where airflow and sun protection matter most.

Key Features

• Material: Woven HDPE construction resists fading and fraying so the fabric stays serviceable through sun exposure.
• UV protection: Blocks up to 95% of harmful UV rays, helping lower surface temperatures beneath the sail by roughly 10 to 15 degrees.
• Breathability: Water permeable design allows rain and airflow to pass through, reducing pooling and wind load on the fabric.
• Hardware-ready: Stainless steel corner D rings attached to heavy duty white webbing make anchoring to poles, walls or trees straightforward when paired with proper hardware.
• Custom sizing: Available in a range of sizes and custom options so buyers can match irregular spaces, provided measurements are taken carefully.

Who It's For

The ShadeMart 9 ft x 17 ft rectangle shade sail suits homeowners, renters with yard or balcony space, and small businesses needing a low-profile shade solution for seating areas or carports. It is particularly good where ventilation and reduced heat are priorities because the fabric is breathable and water permeable.

Those who need complete waterproofing, an exact factory-cut geometric rectangle, or integrated fasteners should look elsewhere or budget for a hardware kit and professional installation; customers reported occasional variation in measured shape and recommend precise site measurement before ordering a custom size.

Pros & Cons
