In 1931, the Grays’ lineup featured five future Hall of Famers. \nDesigned in the style of the raglan baseball tees worn in the mid 20th century, this lightweight, 185gsm cotton tee has raglan sleeves and is finished with a vintage-style screen print of the GRAYS lettering across the chest. Garment washed for that soft, broken-in handfeel.\nIn partnership with the Negro Leagues Baseball Museum (NLBM), we are proud to offer this cotton tee. A portion of proceeds from this product will support the NLBM in Kansas City.
