ShadeMart 11 ft x 16 ft Green Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 11 ft x 16 ft Green Sun Shade Sail, the bottom line is simple: this is a practical, heavy-duty fabric sail for anyone who needs reliable UV protection and breathability over patios, carports or pool areas. The biggest reason to buy is the combination of woven HDPE fabric and stainless steel corner D rings, which delivers durable sun blockage while allowing water and air to pass through so heat is reduced without pooling. It is best for homeowners or renters who want a low-maintenance shade solution rather than a fully waterproof canopy.

Key Features

• Material: Woven HDPE fabric provides a strong, tear-resistant surface that blocks a large portion of sunlight while staying lightweight for easier handling.
• UV Protection: Rated to block up to 95% of harmful UV rays, the sail materially reduces sun exposure and lowers the temperature in covered areas.
• Hardware: Stainless steel D rings attached to heavy duty white webbing offer secure anchor points and corrosion resistance for outdoor use.
• Breathability: Water permeable design allows rain and air to pass through, preventing water pooling and promoting airflow beneath the sail.
• Custom sizing: Available in multiple sizes and custom options so buyers can match the sail to patios, pergolas or carports when they measure carefully.
• Styling: Rectangle shape and color options let the sail function as a decorative element while providing practical shade.

Who It's For

The ShadeMart rectangle sail suits homeowners, renters or small businesses that need effective sun protection for outdoor seating, play areas, pools or carports and prefer a breathable, non-waterproof canopy that reduces heat. Installers who want corrosion-resistant attachment points will appreciate the stainless steel D rings and heavy webbing for long-term outdoor exposure.

It is less suitable for buyers who need a fully waterproof cover for continuous rain protection or who cannot allow any deviation from exact rectangular dimensions; customers should measure carefully because manual measurement variation is possible and some buyers reported sizing differences.

Pros & Cons

• Durable woven HDPE fabric with stainless steel D rings and reinforced webbing for secure anchoring.
