Reproduction of the denim jacket issued to US Navy sailors in WWII. The jumpers were used for work duties in moderate weather, and were general issue throughout the fleet. They are a simple garment, with a shawl collar, two pockets, and removable buttons. ATF's jackets are identical to the originals, using the same weight and shade denim, sewn with dark navy blue thread, double needle chain-stitch construction, realistic contractor labels, and perfectly reproduced Navy buttons. Like their Chambray shirts and dungaree trousers, once these are worn a bit, there will be no way to distinguish them from the originals. From a collector standpoint, they are frightening realistic.These are a loose fitting jacket and the sizing is accurate. Washer/ dryer safe.
