Wool is superior to all other fibers in its ability to handle body moisture in both warm and cool environments. The porosity of the cells in the outer layers of wool fiber allows them to quickly and efficiently absorb and evaporate moisture. In fact, the fibers can absorb up to 30% of their own weight in moisture — ten times as much as any synthetic fiber — without feeling damp or clammy. The porous structure also explains why wool is such a good thermal insulator, not to mention the mesh of the fibers, which creates millions of air pockets that further help to regulate temperature and humidity.
Wool is a naturally strong fiber. It can bend back on itself 20,000 times without breaking. Compare this to cotton at 3,200 times. Due to its unique chemical structure and natural moisture content, wool is naturally fire-resistant. And despite its natural moisture content, wool’s dry, porous nature repels mildew and dust mites.
