The classic dad hat for big heads is made of brushed twill and has an adjustable Velcro (hook and loop) strap in the back. This large hat is low profile and unstructured which means it will take to the shape of your head instead of sticking up on its own. You'll instantly have the worn look with the pre-curved visor. Made of 100% cotton. Fits hat sizes from 7 3/8 - 8 1/2 (23" - 26.5" head size). Approximate bill length: 2.75".
