Designed to give great everyday performance, even in demanding military, security and police work, UphillSport PATROL L2 Reinforced Liner Socks are made with Coolmax for exceptional breathability and moisture-wicking properties. Rather than absorbing sweat, it allows moisture build-up to pass through to the outer sock, and then dries quickly, protecting skin and keeping the wearer’s skin comfortable and dry. Light, at only 39gms, these UphillSport Patrol Socks, designed and made in Finland as part of their Tactical collection are thermal grade 2 for a cool feel. They have a fine, smooth knit with added durability in the foot. Smooth toe seams ensure a comfortable feel that helps prevent rubbing and blisters.
