These PermaCool socks are designed to keep your feet cool and dry in hot weather. Utilizing evaporative cooling technology, they scientifically boost evaporation to provide a cooler and drier experience than conventional socks. The socks feature channeled fibers that quickly move moisture away from the body, enhanced airflow for increased air permeability, and low absorption fibers to reduce moisture retention. Made from 92% Polyester and 8% Nylon, they are available in multiple sizes and colors to suit your needs. These socks are ideal for everyday wear and are machine washable.
