Description
The Portwest women's thermal trousers (B125) are a thermal base layer that protects women from cold working conditions. The trousers are designed for those working in cold environments, such as construction, logistics, outdoor services, or industry. Thanks to the polycotton material, they function as a first layer under workwear and help maintain body temperature.
For what type of work are the Portwest B125 women's thermal trousers suitable?
The B125 is suitable for women working in cold outdoor conditions or unheated spaces, such as construction sites, warehouses, road management, or outdoor services.
The trousers function as a base layer under work trousers or overalls and are therefore highly versatile. Because they meet EN 14058 Class 2, they offer a measurable thermal insulation value of at least 0.140 m².K/W (Clo 0.9). This makes them suitable for moderately cold conditions where extra heat retention is needed, but heavy polar clothing is not practical.
What does EN 14058 Class 2 mean for the Portwest B125 thermal trousers, and when should you choose this model?
EN 14058 is the European standard for garments that protect against cold environments. Class 2 indicates that the trousers have a thermal resistance of at least 0.140 m².K/W, which corresponds to a Clo value of 0.9.
Choose the B125 when you need a lightweight, comfortable base layer that retains heat without adding too much bulk. Unlike standard cotton underwear, this model offers a certified insulation value, making it suitable for professional use in cold working situations.
The trousers are made from a soft blend of 50% polyester and 50% cotton (200 g/m²) for a comfortable, skin-friendly fit.
