Originating from the base of the beloved LUXURY 200 but with a different blend of materials. Merino wool, elastic fiber and polypropylene make these socks incredibly comfortable and specific for the winter season. - The elastic fiber hugs the entire foot and runs all the way down the sock to provide light pressure. Added to it is merino wool with its very high thermoregulating capacities, and polypropylene that increases its abrasion resistance.Care:- Do not bleach- Dry after washing at a temperature not exceeding 60°C- Do not dry clean- Do not iron
