About Us

What Marines call an Oh Three is actually a Zero Three, but that doesn't roll off the tongue very well. It's the prefix for all Military Occupational Specialties (MOS) in the U.S. Marine Corps Infantry. The Oh Three is followed by two more digits. You will often see X's used as placeholders. In other words 03XX. We here at Oh Three XX Gear know what it means to love and serve the greatest country on Earth. If you have ever worn a uniform, any uniform, or if you just love this great nation, you will find something here that you love. Our products are designed by Veterans for all Defenders of the Constitution. For Patriots

We are a small, USMC Veteran 0311-owned business that designs apparel and accessories to honor the service and sacrifice of all who have worn a uniform. If you are counted among that select few, we sincerely thank you for your service, civil or military. You are the reason the U.S. is the greatest nation on Earth. Semper Fi

We are committed to reducing waste and to offering our products at the lowest possible cost. In order to accomplish this, most of our products are made to order. This means a slightly longer wait time for you but we assure you it is worth it. Most Oh Three XX Gear ships within 3 - 5 days of your order.



***Hey y'all, we've gone rogue and we are in NO WAY attempting to imply United States Marine Corps endorsement of our products. And, because 32 CFR 765.14 demands it, neither the United States Marine Corps nor any other component of the Department of Defense has approved, endorsed, or authorized this product (or promotion, or service, or activity). Like I said gang, and most other Oh Threes know, we do our own thing.***
