Our friends over at Rock-N-Jocks recently just released the New Era Boston Celtics Shamrock Hats and now they are back with yet another Boston Celtics cap. Here we a 59Fifty Fitted Hat which turns back the clocks with the old school Boston Celtics script logo. The New Era hat is all green with the Boston Celtics script logo in white and outlined in green. The back of this hat has the embroidered shamrock logo in white as well. The hat is limited to only a total of 30 pieces and the only place to get yours is at Rock-N-Jocks.
