ShadeMart 17 ft x 19 ft Brown Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 17 ft x 19 ft brown rectangle sun shade sail is examined for homeowners and outdoor owners who need reliable UV protection without a rigid structure. The bottom line: it is best for patios, carports, RV cover and poolside shading because the woven HDPE fabric blocks up to 95% of harmful UV rays while remaining water permeable and breathable. The review focuses on build quality, ease of installation, and real-world performance rather than marketing claims.

Key Features

• Woven HDPE fabric: Provides high UV blockage and long-term resistance to fading while allowing airflow to keep shaded areas significantly cooler.
• Stainless steel D rings: Heavy duty corner rings attached to reinforced white webbing provide solid anchor points for secure mounting.
• Water permeable design: The sail lets water and air pass through which prevents pooling and reduces wind sail effect in breezy conditions.
• Custom size options: A range of sizes are available so buyers can order a size that closely matches their patio or carport, provided they measure accurately beforehand.
• Rectangle styling: A simple rectangular shape integrates with many outdoor layouts and doubles as a decorative canopy for patios, pergolas and pool areas.

Who It's For

The ShadeMart rectangle sail is aimed at homeowners, RV owners and small business operators who want UV protection for outdoor spaces without installing rigid roofing. It is well suited to patios, carports and poolside areas where airflow and evaporative cooling are helpful, and where a breathable fabric is preferred to a waterproof cover.

Those who need a completely waterproof canopy, or who require exact cut-to-the-inch sizing for a built-in structure, should consider a different product. Also buyers expecting exact color matches may find some variation, so verify the shade sample if color precision is critical.

Pros & Cons

Pros

• Blocks up to 95% of UV rays and lowers temperatures in shaded areas, making it effective for sun protection.
• Durable construction with stainless steel D rings and heavy duty webbing enhances longevity and anchoring strength.
• Breathable and water permeable fabric prevents water pooling and reduces wind loads compared with solid covers.
• Easy to install with the proper hardware and adaptable to poles, walls, trees or roofs.

Cons

• Not waterproof, so it will not keep rain out of covered spaces during heavy downpours.
• Reported color and size can vary slightly due to manufacturing and manual measurement, so exact match expectations may not always be met.
