All weather wool boot sock
The "Environmental Sock System
" is a multi component sock system consisting of a Coolmax® liner sock and two unique reversed terry nap U.S. Wool and Polypropylene blend boot socks. Both liner and wool socks must be worn together to make the system work.
The "Coolmax®" liner sock promotes the natural cooling action of the body by wicking away moisture, keeping the foot ultra-dry and comfortable while minimizing foot odor and bacteria build-up. Soft, lightweight Coolmax® fibers transport heat and moisture away from the skin more effectively than any other fibers.
