ShadeMart 13ft x 17ft Green Sun Shade Sail UPF50 Rectangle

In this review of the ShadeMart 13' x 17' Green Sun Shade Sail, the conclusion is straightforward: it is a practical, heavy duty rectangle canopy for homeowners who need reliable sun protection and airflow over a patio, carport, or pool area. The sail's woven HDPE fabric and stainless steel D rings deliver durable construction, and the breathable, water permeable design blocks up to 95% of UV while noticeably lowering temperatures. This review examines build, usability, fit, and real-world performance to help decide if it suits your outdoor shading needs.

Key Features

• Woven HDPE fabric: provides a durable, UV resistant surface that reduces sunlight and helps keep shaded areas cooler.
• Stainless steel corner D rings: attached to heavy duty webbing for secure mounting and long-term corrosion resistance.
• Water permeable design: allows rain and air to pass through so water will not pool and the canopy stays breathable in varied weather.
• UPF50 sun protection: blocks up to 95% of harmful UV rays, making it suitable for prolonged outdoor use around people and furnishings.
• Custom size options: available in multiple sizes so you can order a sail closer to your installation needs when standard sizes do not fit.
• Rectangle styling: offers a clean, architectural look that integrates with patios, pergolas, or carports while acting as a decorative element.

Who It's For

The ShadeMart rectangle shade sail is best for homeowners, renters, or small business owners who want an affordable, heavy duty canopy to cool outdoor seating, a carport, or poolside area while still allowing airflow. It is well suited to installations anchored to posts, trees, walls, or roofs when paired with the proper hardware kit.

Those who need a fully waterproof structure, a precise factory-cut geometric shape for formal architecture, or installation without any measuring should look elsewhere; this product is water permeable by design and sizes can vary slightly due to manual measurement and customization.

Pros & Cons

Pros

• High density woven HDPE resists fading and offers strong UV protection for shaded areas.
• Stainless steel D rings with heavy webbing make mounting sturdy and reliable over time.
• Water permeable fabric prevents water pooling and maintains airflow in mixed weather.
• Custom sizing options let you fit nonstandard spaces more closely than off-the-shelf sails.

Cons

• Not waterproof, so it will not keep heavy rain entirely out of covered areas.
• Some customers report size or shape variations due to manual measurement, so precise fitting can require extra care.
