WLS is a short and thin trekking sock from single knitting containing merino wool, which is a unique natural material. A mesh zone is fitted across the entire instep area, which provides air circulation and moisture transport. The toe and heel sections are made of a two-layer smooth knit, which provides high mechanical resistance. Wool has excellent antibacterial properties and reduces unpleasant odours.  70% MERINO, 10% SILTEX, 13% POLYAMID, 7% LYCRA
