Viking Eiger is a model of men´s thermoactive underwear, perfect as the first layer of clothing. Thanks to the minimization of the number of seams and the elastic and technical fabric, the set perfectly fits the body shape. The result is comfort and freedom of movement as well as no abrasions or skin damage during physical activity. The underwear set has been designed in a way that sweat and moisture are quickly transported to the outside and at the same time the thermal balance is maintained, without overheating or cooling down the body. The composition of the knitted fabric (55% Polyester / 37% Polyamide / 8% Elastane) helps to minimize odor, adjust to the body structure and heat it up.
