These are genuine British Navy Knee High Socks issued for official service. Naval Issue and Material Issued to Royal Navy personnel, these British Navy Knee High Socks were built for severe conditions at sea. They feature a 70% wool and 30% nylon blend, combining natural temperature regulation with extra synthetic strength. Wool retains warmth even when damp, making it ideal for wet maritime environments and cold boot wear. Knee-High Fit and Durability The extended knee-high length provides complete calf protection inside tall combat or work boots. A full ribbed knit structure holds the leg secure without cutting off circulation. High-wear contact points at the heel and toe are heavily reinforced to prevent friction wear and premature holes during long marches. Authentic Details and Care Finished in a natural off-white shade, each pair bears an authentic stamped numeral mark on the sole used for naval quartermaster sizing. These surplus items may display minor storage marks or age discolouration. A quick initial wash restores freshness for field use, bushcraft, or cold-weather work. Equip your footwear with proven naval issue wool protection for demanding outdoor work.
