Most synthetic clothing fibers strengthen body odors, because they are a breeding ground for bacteria. Sweat itself is odorless. It’s the bacteria that make you “smell like sweat”. Wool reduces the chance of odors for an important part, because the fibers quickly absorb the sweat and releases it to the air. Unlike most other natural and synthetic fibers, wool does not retain moisture or odors. Simply hang it out and let it air and your wool socks are fresh again! In addition, the outer layer of the wool fiber contains a high concentration of fatty acids with antibacterial properties.
