Brubeck Women's Comfort Wool is the ultimate leisure underwear. It is made from the finest natural raw materials in the world - merino wool. It is very soft, feels gentle against the skin, and does not itch. Merino wool is also very thin, with fibers measuring only 16.5 microns, which is more than four times thicker than an average human hair. The thinner and denser the wool, the better it insulates thermally. The fibers in the Comfort Wool Collection by Brubeck are the finest Australian merino wool. Because the wool is highly elastic, it fits the body perfectly, is gentle on the skin, and leaves no marks thanks to pressure-free seams and flat seams. Composition: 57% polyamide, 41% merino wool, 2% elastane.
