Why We Like It

This tech sock is powered by 37.5’s patented activated carbon technology to keep feet warm and dry regardless of activity. Activated by your body heat, these socks pull moisture away from your skin and evaporates it fast, minimizing both hot spots and cold toes.


Naturally derived from coconut shells, 37.5 technology adds surface area to the yarns used to create the socks, dramatically speeding dry time and evaporation.
