DAD HAT PRODUCT DETAILS: This hat is made from 100% bio-washed chino twill, a very comfortable, soft, and sturdy denim-like fabric that does not wrinkle. The 100% vegan PU leather patch has the look and feel of genuine leather. It has a low profile for that classic "dad hat" look, and a d-ring closure on a fabric hideaway strap for a perfect, adjustable fit. Small variances of 0.5" in size are possible.
