Do you like book? Maybe it's just me, but I feel there's something hip and avant-garde about a hat that says "book" instead of "books". 100% cotton bright green baseball hat (structured front panels) with white embroidery has something of a street wear vibe. Adjustable buckle and strap. One size fits most. Designed by me in Tucson, Arizona and manufacturers in China. I have 4 other bookish hat designs. Check them out!
