Flat Bill Cap ~ 100% Polyester 6 Panel ~ 2 Sizes / Choice of Black, Navy, White These flat bill hats are very durable and long lasting caps constructed of heavy-duty 100% polyester. The caps are constructed with 6 panels that are sewn together to form a sturdy hat that?s also very stylish. Flat bill hats are a style of baseball hat, and they are largely recognized for their flat or strait brim located on the front. Flat bill hats are distinguishable from typical baseball style hats because they have a very flat visor, also called a brim or bill, which is usually kept flat, straight and stiff by a thick piece of paper based material that?s sewn into the bill. There are usually several rows of stitching on the bill that only add to the stiffness and durability of a flat billed hat. The visor portion of a baseball cap was traditionally designed to shade a baseball player?s eyes from the sun. Today, the different ways to shape your bill are more of fashion statement than a functional necessity.
