These khaki chenille pattern fedora hats with a braided band are a great addition to your wardrobe. To wear them, simply place the hat on your head. They are one - size - fits - all, so they should fit most head sizes comfortably. When it comes to maintenance, you can use a soft brush to gently remove any dust or debris. Avoid getting the hats wet as the polyester fabric may not dry evenly. Be aware that this product contains chemicals like cadmium, lead, and nickel, which can be harmful.
