With the Next to Skin series, Rukka employs the concept of multifunctional high-tech laminates in the functional undergarments sector. An outer layer of Windstopper membrane keeps the wind out while retaining breathability. The inner, knitted layer conducts moisture away from the skin, preventing chill-out through evaporation. WINDSTOPPER N2S (Next-to-skin) products can be worn either directly on the skin to serve as functional undergarments or above the functional underwear to form an additional, warming layer.
