The Original Busted Knuckle Hat. These Hats are quality built using 63% Polyester / 34% Cotton / 3% Spandex. The spandex gives them some flex so they look like a fitted hat but give you some flex for comfort. They are available in Youth thru 2XL sizes to fit any noggin. We also have a a few different color options available as well. Our favorite is the black because it doesn't show grease. All are adorned with the Knuckle and Wrench Logo on the Front and a small BK letter Logo on the Back.
