Ebbets Field Flannels is known for its faithful reproductions of vintage baseball paraphernalia—each historical team logo is carefully researched and authenticated by the experts and aficionados at Ebbets before being applied to the cap, a design based on an original 1950's-style hat. Our designers worked closely with the EFF team to recast these vintage favorites in soft brushed twill (an update to the original wool style) in exclusive-to-J.Crew colors and topped things off with an adjustable closure in back. During World War II, many professional ball players joined the service and played for amateur teams on their military base. The Great Lakes Naval Station was one of these teams, and they just happen to have fielded such baseball icons as Bob Feller. Not bad for amateurs.
