BILLY KIRK and EBBETS FIELD put in some work on this collab and came up with the “No. 323” 5-Panel cap. The cap is all olive and features the BILLY KIRK and MAUL logo on the front panel. The sides features embroidered grommet ventilation and the strap in the back is a tan leather with metal adjusting clasp. The underbill contrasts in green and made of satin material. Act quickly as this cap is limited to only 30 pieces.
