MLB keeps on with one of their yearly baseball cap releases, this time for St. Patrick’s Day. Show some love for your favorite team by rocking their hat from the MLB St. Patrick’s Day 2023 59Fifty Fitted Hat Collection. The dome and uppervisor are in lucky green. They made these hats for sunny days, with the side and rear panels in mesh material. The front design features dark green and gold embroidery of the team logo. The undervisor of the bill is in gray to add a neutral tone to the hat design. On the left panel is the New Era Flag, and at the back is the MLB Batterman. View the whole collection here.
