Wool is a textile fiber obtained from sheep and other animals. It is an anallergenic and breathable fiber that regulates moisture and body heat, protecting from both hot and cold weather. It is also a material that lasts very well over time.
Hand washing and air dry help prevent damage. Otherwise, select a wool or delicate cycle in your washing machine with cold water. Do not use any softening products. You can also place the garment in a mesh laundry bag.
