RNC is a sock made from a single layer plush knit. 60% of the sock is made of COOLMAX - polyester material, a special, non-absorbent four-channel polyester fibre which removes moisture from the surface of the skin to the top layers of the sock. The heel and toe is reinforced with a double layer plush knit, which  has been designed to provide better thermal insulation and protection against blisters.  Elastic is fitted around the instep area.
