Viking Arcto is a model of men's underwear, made of a special type of Polartec® fleece. Thanks to this, it has perfect thermal insulation, breathability and the flow of moisture in the form of water vapor is maintained. The product dries quickly, minimizing heat loss during exercise. The great advantage of knitwear is its light weight. In addition, you can put the underwear in the washing machine, as it will maintain its appearance and quality even after many washes, thanks to the pilling resistance. The Arcto Set does not electrify, its cut ensures proper fit to the body shape, the extended body and stand-up collar ensure comfort of use at low temperatures.
