These heavy weight thermal socks are up to 7 times warmer than a basic cotton sock making them perfect for wading in cold water conditions. Heat Holders are made from a specially developed heavy bulk yarn which has extreme thermal qualities. The advanced fibers provide high performance insulation against cold with superior moisture wicking abilities. The inside of each sock has been intensively brushed so it not only feels sensationally soft, but also traps warm air close to the skin, keeping your feet warmer for longer and for all-day warmth and comfort. Content: 91% Acrylic, 5% Nylon, 3% Polyester, 1% Elastane.
