How often do you release new designs?

I have my own military design. Can I submit it?

Yes, we always welcome creative ideas. If your design aligns with the Brothers in Arms philosophy, you are welcome to submit it.

If your design convinces us, it could become part of the Brothers in Arms collection and you’ll receive a Hoodie for free.

Can only people who have served wear your T-Shirts?

No, our Printed T-Shirts are for anyone who stands by their values and follows their own mission. Our community includes soldiers, athletes, adventurers, and determined individuals from all walks of life. Brothers in Arms is about attitude, not your résumé!
