Wool
Wool is mainly made from sheepskin and is a natural fiber. It has a natural heat regulation property.
Wool can absorb water vapor in the fiber core, but its surface repels water. Wool can absorb around 33 percent of its dry weight without feeling damp. It wicks away moisture much better than cotton.
The fibers of wool are very elastic and therefore they absorb dirt only poorly and hardly ever crease. In addition, wool has a high insulating capacity, is hardly inflammable, very colour-fast and only absorbs the smell of sweat to a small extent.
