Our Shadow Military baseball cap features a Shadow embroidery design on the base of the cap and a 3-D High Definition embroidery logo on the crown. This technique results in a "shadow effect" of either the original embroidered design or other picture, which is eye catching and very unique. Additionally, both the edge and top of the sandwiched bill is embroidered. A hook & loop closure, with embroidered text, helps to keep this cap on your head. 100% Acrylic.
