New Era is proud to present the Official On-Field MLB Cap, the classic on-field style worn by the Seattle Mariners. The fitted 59FIFTY is New Era's authentic cap featuring a highly structured 6-panel crown, flat brim and closed back. Each cap is sized to provide a comfortable fit for both player and fan and features sewn eyelets for breathability. The cap is decorated with the team emblem sewn in relief on the front of the crown and a contrasting New Era flag sewn on the left side. Finally, the batsman logo, emblem of the MLB, is embroidered on the back panel.
