UPF (Ultraviolet Protection Factor) is a filter that, when applied to fabrics, provides effective protection against the sun's harmful rays.

CARBON DRI® technology by Surfanic is an advanced system using activated carbon in thermal underwear. It features exceptional vapour permeability of up to 25,000 m2/24h and has antibacterial and anti-allergenic properties that prevent the growth of bacteria and fungi, eliminating unpleasant odours. In addition, the underwear offers UV50+ protection, protecting the skin from harmful UV rays. Made from a soft, stretchy fabric with flatlock seams, CARBON DRI® underwear dries quickly and wicks away moisture effectively, keeping you warm and comfortable even during prolonged use.
