Information Our Officer Shirt references various historical American service uniform overshirts combined with an updated fit and trademark 3sixteen detailing. Compared to our Fatigue Overshirts and BDU Jackets, the Officer Shirt has a more cropped and wider body which gives it a jacket-like feel that you can easily layer over another button down or t-shirt. For the fabric, we sourced a heavyweight Japanese HBT fabric that's been mill washed for a softer, broken-in hand while still being hefty. Made in USA.
