Original features include narrow epaulettes, snap front pockets, collar snaps and under arm eyelets for ventilation. The zipper and snaps are solid brass. Also features bi-directional knitted wool on cuffs and waistband which helps the jacket retain shape, whilst helping to keep out cold winds. Side entry hand warmer pockets, internal pocket and a durable nylon lining make this an ideal three season garment. Sizing is based on Chest Size in inches. In our experience the A-2 runs a little small, so if in doubt please order the next larger size.
