The American outback-style Bison Leather Hat is made of an extremely soft, almost buttery bison leather. It offers ultimate sun and rain protection while being one of the softest, most comfortable hats you'll ever wear. Featuring a super comfortable removable sweatband liner that attaches securely with velcro tabs sewn-in to the hat. Easily swap the liner for a half or full-size reducing sweatband (included with purchase) to achieve the perfect fit.
