The main fabric consists of a unique, GRS certified, 80% recycled poly and 20% virgin wool blend. The interior is fully lined with soft satin and a 100% cotton headband, which helps prevent itching and regulate temperature. To wash your Fargo Hat, spot clean or wash by hand with cold water. If you must use a washing machine, use a delicate cycle with cold water. Always air dry at room temperature. Tio Lee cannot accept returns or exchanges for product that has been washed or dry cleaned. Tio Lee donates $2, for every hat sold, to The Brooklyn to Alaska Project. Learn more about their amazing organization on our Friends page.
