Inspired by the Type A-1 sweater issued by the United States Army Air Force during the Second World War, the Journeyman Sweater continues a tradition of excellence. Although issued to engineers and mechanics, the A-1 saw quick adoption by pilots and other aircrew for use under their Type A-2 leather flight jackets. The Journeyman Sweater continues the tradition of the A-1, updating the style with contrasting ribbing details, our signature slotted buttons, and a 70% Wool/30% Nylon yarn for long-wearing durability.
