Pioneers, groundbreakers, sporting legends. The San Francisco Sea Lions were one of the great Negro Leagues teams blazing a trail for justice in sports, and we're repping that spirit with this super-soft tee. Mark a historic era in baseball's long march toward equality, and pay homage. A portion of proceeds benefits the Negro Leagues Baseball Museum, the world's only museum dedicated to preserving and celebrating the rich history of African-American baseball and its impact on the social advancement of America. The privately funded, 501 c3, not-for-profit organization was established in 1990.
