Portwest C370 MeshAir™ Vest: Extreme Ventilation Engineering and Class 2 High Visibility

The C370 is a high-visibility (Class 2) vest designed specifically for operations in hot climates and industrial environments with high thermal load. Made entirely from technical mesh fabric MeshAir™, this garment prioritizes thermal homeostasis management over mechanical resistance. It is standard equipment for logistics personnel, warehouse operators, and road workers who require a lightweight visibility barrier that does not compromise the body's evaporative cooling capacity during high-intensity physical workdays.

Technical Features and Operational Capabilities

• MeshAir™ Ventilation Technology: The open mesh structure (150g) allows constant and direct airflow to the skin, optimizing sweat evaporation and reducing the risk of heat stress compared to flat fabric vests.
• Certified Visibility (EN ISO 20471 Class 2): The configuration of the reflective tapes guarantees operator detection in active traffic environments or warehouses with heavy machinery. As a Class 2 product, it offers a larger surface area of fluorescent material than Class 1 vests, maximizing visual detection distance.
• Quick-Access Ergonomics: Front hook-and-loop (Velcro) closure system designed to allow immediate donning or doffing, facilitating transition between protected areas and operational risk zones without losing production time.
• Generous Fit Design: Wide cut allows for comfortable wear over base layers or work uniforms without restricting user movement, ideal for dynamic field maneuvers.

Safety Warning and Limitations of Use

IMPORTANT: This is a high-visibility garment for hot climates. It is NOT flame-retardant, is NOT anti-static, does NOT offer thermal protection against cold, and has minimal mechanical resistance. Because the fabric is open mesh, its use near machinery with moving parts, shafts, or rotating elements is strictly prohibited, as the risk of snagging and entanglement is high. It does not replace a structural safety vest for high mechanical risk tasks.

Maintenance and Care Instructions

• Washing: Machine wash at 40°C maximum. Use neutral detergents. DO NOT use fabric softeners, as these will clog the MeshAir™ mesh and degrade the retroreflection of the bands.
• Drying: Air dry. INDUSTRIAL TUMBLE DRYING IS PROHIBITED; excessive heat will shrink the mesh and deform the reflective tapes, nullifying EN ISO 20471 certification.
• Ironing: DO NOT IRON. Direct heat contact will melt the polyester of the mesh and destroy the reflective properties of the bands.
• Inspection: Due to the inherent fragility of the MeshAir™ fabric, it must be inspected daily before use. If the mesh shows perforations, fraying, or the reflective tapes show signs of detachment, the vest loses its visibility capacity and must be replaced immediately.

Inventory and Sizing Information

For accurate inventory management and correct ergonomic fit, this product is available in individual sizes: S, M, L, XL, XXL, and 3XL. It is recommended to select the size based on the measurement over the underlying work garment to ensure mobility and compliance with the visibility standard.
