The Marinepool functional pants Thermo Trousers are designed as a 1st layer (base layer) especially for cold weather. These highly functional long-sleeved thermal trousers with breathable Cooldry fibre structure for improved moisture transport keep you warm even when damp. Thanks to their breathability, the trousers can also be worn in warmer weather or during sporting activities. The specially flat-stitched seams of the trousers ensure optimum comfort even during activity and prevent chafing on the skin.
