Headwear store My Fitteds concocts a throwback baseball cap that features a previous MiLB team name with its former MLB affiliate. Here is the Appleton Foxes x Seattle Mariners Alex Rodriguez 59Fifty Fitted Hat. The crown of this cap has midnight navy panels and a pure aqua button on top. The front embroidery features the Appleton Foxes logo while the right panel has a Seattle Mariners side patch. The uppervisor of the bill is in pure aqua, while the undervisor is in placid gray to add a neutral tone. The New Era Flag is subliminally embroidered on the left panel. The MiLB Batterman appears in tri-color embroidery at the back. Available here.
