Long-sleeved unisex shirt with a small collar made from high-quality merino wool, featuring a short zipper for airflow. The material is produced using a circular knitting process without longitudinal seams and offers excellent insulation properties, keeping you warm even when damp and in extremely cold temperatures. This thin functional underwear is designed to be worn directly against the skin as a moisture-wicking base layer. Woolpower products truly shine here, as the material maintains the body's heat balance while also transporting sweat away. This thermal underwear provides optimal cold protection depending on the activity, in temperatures ranging from +10 °C to -20 °C. It is made from knitted terry fabric.
