Hat Club dives deep into Major League Baseball history with their latest exclusive release, the AL Charter Member 59Fifty Fitted Hat Collection. This hat features three of the charter members that are still in their team’s city: the Detroit Tigers, Boston Red Sox, and Chicago White Sox. These retro hats go back to 1901, the year the American League was founded. The front design features the customary cap insignia. On the right panel is the AL 100th Anniversary patch, while the left panel has the New Era Flag. Hat Club also added an MLB 125th Anniversary to this drop. Available today, February 25 at the Hat Club webstore.
