The body is made of 100% naturally water repellent wool and rarely gets wet inside. Surface moisture from dew, rain or snow quickly dries in the open air. Wool is also naturally dirt and mold resistant. Generally, a good brushing is all that's needed. Otherwise, work the spot with mild soapy water, then rinse and air-dry. Do not use a washing machine or dryer.
