If you are want to know about NJA cold wx stuff- no leather here. They made us get a super expensive designer overcoat and pay an extra $300 or so from our uniform allowance for the liner to make it usable in the winter whether we wanted the liner and coat or not. We have a choice of a v neck sweater, a cardigan, or a v neck sweater vest if you want something a little warmer over your shirt in the winter. I would vote for leather in a heartbeat, but it is not an option no matter how much the uniform committee tried.
