I have a 7 3/8 one from when I was at NPS. Back then you could wear SDBs or relaxed SDBs with the Ike and black piss cutter. Carry around a combo cover or a piss cutter that you tuck in to your belt? Easy decision.I might actually have a 7⅝ garrison cap somewhere. Not even sure if that came with the Johnny Cashes we got back in OCS though. It was back in the last millennium, which was a pretty long time ago.
