Hat Club veers away from the crowd-favorite neon-colored undervisor ballcaps for their latest batch, the Hat Club MLB August 25 59Fifty Fitted Hat Collection. The first two hats off this drop are throwback pieces: the Padres Friar Prototype and the Brewers Barrelman. They then came up with a New York Yankees hat in its official navy blue team color with white cap insignia. All three mentioned have kelly green for the undervisor. Capping off the drop is the MLB Umpire hat in black. It features a big version of the MLB Batterman logo for the front design and a gray undervisor for the bill. Get yours at hatclub.
