Wear warm. the material used combines two very important requirements for keeping our body warm in very cold weather - the bottom layer made of polypropylene fibre immediately draws sweat away from the skin and the top layer made of fine merino wool yarn ensures the necessary thermal comfort. merino wool in particular has an excellent ability to insulate the heat generated. It finds a use when you want to stay warm even though you don't do a lot of physical activity.
Functional underwear for sports, physical activities in cold weather or motorcycle travel when temperatures fluctuate more, for example in spring and autumn. Also suitable for all light outdoor activities, hikes or walks in the woods, hunting and fishing.
The fine polypropylene fibre used on the underside of the knit is non-absorbent, thus wicking your sweat to the surface of the knit, not cooling on the skin and helping to provide thermal comfort to your body. The active ingredients, i.e. silver ions, are contained in the entire volume of the fibre, are safe, do not irritate your skin and do not cause allergies. Silver actively reduces the growth of bacteria and thus provides permanent and long-lasting protection against odour.
The second layer, made of fine merino wool, serves as thermal insulation. This underwear is therefore a suitable choice for very cold and frosty weather.
Our products do not need to be washed after each use and thus actively contribute to environmental protection. :)
