The Portland Sea Dogs celebrated Maine's bicentennial in 2020 by wearing specially designed uniforms that depicted the original state flag.
The primary logo on this New Era 59FIFTY Fitted Cap features an embroidered, emerald green version of the Sea Dogs primary logo paired over the state of Maine, and on the right side, an emerald green pine tree and a blue star in the upper corner from state of Main's flag.
The Portland Sea Dogs is the Double-A MiLB affiliate of the MLB Boston Red Sox.
