ShadeMart 9ft x 13ft Green Sun Shade Sail UPF50 Rectangle - Breathable

In this review of the ShadeMart 9' x 13' Green Sun Shade Sail, the bottom line is simple: this rectangle canopy is for homeowners and renters who want reliable sun protection and airflow for patios, carports, or poolside areas. The sail is made from woven HDPE and is designed to block up to 95% of UV while remaining water permeable, so it lowers temperatures and avoids pooling after rain. Installation is straightforward with corner D rings and heavy duty webbing, making it a practical choice for seasonal or semi-permanent outdoor shade.

Key Features

• MATERIAL: Woven HDPE fabric gives the sail a durable, fade-resistant surface that stands up to regular sun exposure.
• UV PROTECTION: Blocks up to 95% of harmful UV rays to significantly reduce heat and protect skin and outdoor furniture from sun damage.
• BREATHABLE DESIGN: Water permeable and breathable construction allows rain and air to pass through so the canopy does not trap heat or accumulate water.
• HARDWARE READY: Stainless steel corner D rings attached to heavy duty white webbing make anchoring secure and straightforward with the right kit.
• CUSTOM SIZING: Available in a wide range of custom sizes so you can choose dimensions that match patios, pergolas, or carports when measured accurately.
• STYLING: Rectangle shape and multiple color options let the sail act as both functional shade and a decorative element for outdoor spaces.

Who It's For

The ShadeMart rectangle sail is best for homeowners, renters, and small business owners who need a breathable, UV-blocking cover over a patio, carport, pool, or seating area. It suits anyone who prefers a non-waterproof canopy that lowers ambient temperature by allowing airflow and drainage.

Those seeking a fully waterproof shelter, a precise factory-cut geometric rectangle to the millimeter, or an all-in-one mounting solution should look elsewhere; this product is sold as fabric sailcloth with stainless steel D rings and is intended to be used with a separate hardware kit and careful on-site measurement.

Pros & Cons

Pros

• High UV protection blocks up to 95% of sunlight, noticeably cooling shaded areas.
• Woven HDPE material and stainless steel D rings provide solid durability for seasonal and longer use.

• Custom size options and multiple colors allow flexible styling for many outdoor layouts.

Cons
