If you want a baseball cap that you can rock for the last month of summer, here is MLB and New Era with one of their latest collaborative releases. Take your pick from the MLB Storm Gray 59Fifty Fitted Hat Collection. Only half of the 30 Major League Baseball teams are included in this drop, and all caps have grey fabric for the dome and uppervisor. The front team logo embroidery and the commemorative side patch on the right panel are both embroidered in shades of green. The undervisor is in kelly green to keep up with the color scheme. The New Era Flag appears in a grey embroidery on the left panel, and at the back is the MLB Batterman. Check out the whole collection here.
