Devold® Active is an advanced two-layer underwear with superior wicking abilities. The inner layer of Dupont's Thermolite® fibre has more effective wicking properties than most other synthetics and cotton. The outer layer of fine Total Easy Care® merino wool insulates against the cold and absorbs moisture from the inner to the outer layer where it evaporates. This ensures staying dry and warm during the most demanding activities. Devold® Active is extremely soft and is perfect for sensitivity to wool. Devold® Active is Easy Care treated, and you can wash and tumble dry the garments on low temperature.
