Vintage US Military A-1 Extreme Cold Weather insulated jacket by E.C.T. Corporation, dated 1971. This heavy-duty olive drab bomber features a durable nylon shell with a removable insulated liner designed for watchstanders in wet and freezing conditions. The design includes a full-zip front with a snap-down storm flap, two large front utility pockets with snap closures, and adjustable side waist tabs for a secure fit. Notable for its emergency buoyancy feature when the liner is attached, this piece is a rugged example of Vietnam-era functional outerwear. Please note the zipper tape has significant fraying at the base and requires repair to function correctly.
