The USN Overshirt is a shirt jacket style modeled after traditional standard issue 1940s US Navy overshirts. This season's USN Overshirt features a 10.5 oz Japanese indigo canvas woven by Yamaashi Orimono that's been processed with a heavy stonewash treatment to bring out the highs and lows of the deep indigo yarns. The shirt is finished with military-inspired corozo fisheye buttons.
