New Era’s Cooperstown collection features throwback styles. Although most of the time they showcase old team logos, sometimes it’s the little things that make them a throwback classic. 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 fact that fitted aficionados look for.
