70s US army extreme cold weather A-1 jacket

The A-1 is the impermeable counterpart to the iconic A-2 deck jacket and is made for the cold and wet weather that sailors would endure out on the open seas. It features a treated water-resistant nylon shell and is lined with a soft nylon pile. There is a Scovill brand zip front closure, covered with a snap-fastener-secured flap to improve weather resistance. There is a concealed knitted cuff on either wrist, adjustable tabs to tighten the jacket around the waist, and two large hand-warming pockets.
