It’s another expansive collaboration between MLB and New Era with a set of apparel and baseball cap designs. Included in the drop is the MLB Summer Heat 2023 59Fifty Fitted Hat Collection. The hats for this drop feature a two-tone look with the panels in brown corduroy and the button & uppervisor in the team color. The team logo is rendered in raised embroidery. On the right panel is a commemorative side patch, and on the left panel is the New Era Flag. They then added a neutral tone by using gray for the undervisor. Embroidered at the back is the MLB Batterman. Click here to view the whole collection.
