Comfort Wool women's briefs are the highest quality everyday underwear. They are made from the finest natural raw materials in the world - merino wool. They are very soft, feel gentle against the skin, and do not itch or scratch. 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 of the Comfort Wool Collection by Brubek are the finest Australian merino wool. Thanks to the high elasticity of the wool, it does not restrict movement and adapts perfectly to the body. It is gentle on the skin and leaves no marks due to its pressure-free seams and flat seams.
