The Devold Hunting Sock is a thick, durable wool sock. It is made from Merino wool blended with 18% nylon and 2% lycra knitted with a terry-cloth stitch to give a soft inside layer. This sock is used by the Norwegian army, as well as being the favorite sock of hunters, fishermen, and outdoorsmen. This is a dense sock, not 'fluffy', and gives good cushioning as well as insulation. Sock length is 12 inches. Machine wash cool, dry flat. Made in Norway.
