10-4 Gear is run by an officer with over 20 years experience accompanied by artists with a thirst for creating the best shirts and products for our brothers and sisters who proudly hold the thin blue line! You deserve real art by real artists, with direction from the community to create what YOU want! We have been doing custom department and unit shirts for years, and now you can get that experience in your own Police Department, Corrections Team, or First Responder Team.
