Mens Wool Frieze Duffle Sock

This is the duffle sock the military uses when they need to keep warm in Arctic conditions. Designed to be worn inside Arctic type boots, this sock is made of white wool frieze, mothproofed duffle cloth. The sock is 30.5 cm (12") in height and has heels reinforced with white nylon. This sock actually incorporates two socks, one sock inside the other, sewn together around the top.
