About Off Shift Supply Co. I'm Joe, founder of Off Shift Supply Co. I'm a working man — a 19-year law enforcement veteran, still serving as a criminal investigator in Texas. I started the academy in January 2007, and my family has supported me from day one to today. This brand is dedicated to my late father and my late brother, who supported and guided me along the way — and it's for my daughter, who I try to set the example for. Off Shift Supply Co. is family owned and family worn. We price this brand the way I'd want to buy it: solid gear at a fair price, because this brand is for everybody. From the first 10-41 to the last 10-42. A community first. A clothing brand second.
