These fedoras are super easy to use. Just place the hat on your head, and it's ready to go! Since it's one - size, it should fit most people comfortably. When it comes to maintenance, you can spot - clean it with a mild detergent if it gets dirty. Avoid using harsh chemicals as they might damage the 100% polyester fabric. Also, keep in mind the California Proposition 65 warning. Don't expose the hat to extreme heat or moisture, as this could affect its shape and the quality of the chenille pattern and braided band.
