For over 35 years, Engel has been manufacturing underwear and clothing from natural fibers to the highest ecological standards, out of respect for both the skin and for nature. In 2013, Engel developed a new material made from superfine merino fibers that are only 17.5 microns thick combined with exquisite yet robust silk. This fabric is used to produce athletic wear for the ENGEL SPORTS line specially designed for sports and outdoor activities with ultimate comfort. The natural materials ensure that you always feel comfortable warm and dry regardless of activity level. And because of the wool's self-cleaning natural fat lanolin, Engel Sport products rarely need to be washed, but simply hung for aeration after use.
