DURAWOOL™ is a new, innovative, extremely light, yet robust yarn compound that provides an outstanding combination of the properties that make high-tech fibers so pleasant to wear, with the qualities of natural wool. Exceptional manufacturing technology enables Durawool™ to protect the skin from the outside temperature and maintain body temperature at an optimal level. The smooth, tightly-sealed surface structure rapidly conducts moisture away from the skin's surface, so that no moisture can accumulate inside the yarn. The chances of developing foot odor are significantly reduced.
