Thermal & functional underwear – the right basis for everyday work


Thermal and functional underwear is a central component of modern workwear concepts. As the first layer on the skin, it regulates the body climate, reliably wicks away moisture and protects against cooling. Especially when working outdoors, in unheated halls or under changing loads, it makes a decisive contribution to well-being and performance.

In a professional environment, high-quality functional underwear ensures that employees stay dry and warm even in the cold, wind or physical exertion – without heat build-up or restrictions on freedom of movement. It thus creates the basis for safe, concentrated work throughout the entire working day.

Function & Benefits

Thermal and functional underwear for work use is designed for permanent use and, depending on the model, offers:

  • Effective moisture management thanks to quick-drying materials
  • Warming properties at low temperatures
  • Breathable fabrics for a balanced wearing climate
  • Body-hugging fit for optimal freedom of movement
  • Flat seams to reduce pressure and chafing

This creates a functional basis for every additional layer of clothing – from midlayers to weatherproof jackets.

Work-suitable thermal and functional underwear is available in different material combinations, for example:

  • Synthetic functional fibres for fast moisture transport
  • Elastic materials for ergonomic fit and mobility

  • Industry & Production
