Extreme warm means heavier wool so we use the 4 Ply wool for our warmest socks! Our warmest 100 percent wool socks are made of 100% ORGANIC wool in the Dachstein mountain region of Austria in our family factory. These are the original wool Dachstein socks made from 100% boiled wool in a weave so dense they're almost waterproof. We've actually held these boiled wool socks under the faucet for a minute without any water penetrating.  Extra heavy and thick, there are no other 100 wool socks like these in the world----they represent a unique Austrian wool making tradition.  These socks have a reinforced heel and toe and have a beautiful natural weave.  For hiking, climbing, skiing expeditions, or at home on cold days, these are the finest 100 percent wool socks you will ever encounter.
- Our wool socks are hand finished and made of 100% boiled organic Austrian wool in a small family factory in the Dachstein Mountains of Austria.
- These sports socks are warm and essential for comfort in cold weather since wool absorbs 30% of its weight in water and maintains its insulating qualities while also breathing so you don't sweat.
