New Era’s Cooperstown Authentic Collection features throwback styles worn on-field during the Grey Bottom's heyday. Sometimes it’s the little things that make a throwback classic great. In this case, it’s the absence of the New Era flag on the left side of the hat. The New Era branding was not always present on on-field baseball hats, and this pays homage to that look aficionados revere.
