Viking VOLCANIC VOLCANIC men's warm, functional thermal underwear guarantees cosy warmth and comfort. Thanks to their excellent thermoregulatory properties and breathability, they maintain the right temperature and wicks moisture away from the body. The exposed areas are insulated with fleece. Their elastic nature allows it to conform perfectly to your body's contours. The yarn is made from recycled materials, which makes the underwear not only functional but also environmentally friendly, as confirmed by the GRS (Global Recycled Standard) certificate.
