Hirsch Natur's Children's thick socks are made of pure new organic wool are ideal for wearing in rubber boots and when the weather grows cold.
Material: 100% organic virgin wool
Washing: Hand wash with wool wash. These socks do not need to be washed every time they are worn, they can be worn several times before washing. The lanolin in the wool is part of the magic of the wool, it helps to keep feet warm and dry as well as providing deodorizing and disinfecting when allowed to air out between wearings.
