For avid collectors of baseball cap designs with side patches, better check out Sneaker Town as they release a piece with a distinct touch to it. Add a gem to your collection with the Arizona Diamondbacks 2001 World Series Black Grey 59Fifty Fitted Hat. The dome of this hat is in all black, with the Diamondbacks logo embroidered in full color on the front panels. The bill has black for the uppervisor and grey for the undervisor. The 2001 World Series commemorative patch is placed on the left panel, veering away from the usual left side placement of a side patch. The MLB Batterman logo appears in black/white/grey at the back.
