Show your appreciation for your favorite Mlb team with this New Era Boston Red Sox 2025 Mlb Diamond Hero Edition 9FIFTY Snapback Hat. The 9FIFTY is New Era's classic snapback style, with the same shape as the 59FIFTY but an open back and an adjustable snapback closure. This structured fit has the team logo embroidered with raised details on front panels and the contrast-color under visor makes it stand out. The polyester material will keep you comfortable and the flat bill will keep the sun out of your eyes.
