The SHOCKER Snap-back Cap is a 6 panel, cotton twill cap with a 3-D "Puff" embroidery of the "Shocker" logo on front, and a small "13" with lightning bolts embroidered on the side back panel. Adjustable snapback strap fits just about any size head. Please note that we just recently increased the size of the front 3D Puff embroidery, as we think it allows for a better look and cleaner embroidery. Hope you agree.
