Cap with COW BOOKS logo. This shallow-fitting cap, called a jet cap, is made from a sturdy cotton twill fabric and is made of five panels. The felt patch on the front panel is embroidered with “COW BOOKS” in cross stitch. A new multicolor feature has been added that changes the colors of the frame and text. The brim is flat and the size can be adjusted using the strap at the back of the head.
