For the ones who move in silence but make a statement, the Twenty One OPSEC T-Shirt is your encrypted uniform. Featuring a stealthy, bold typeface and a flipped “2” that subtly scrambles the signal, this design speaks in code to those who get it. Minimalist up front, but laced with meaning—this tee is built for quiet operators, digital tacticians, and off-grid minds. Whether you're running black hat or just keeping your profile clean, the Twenty One OPSEC T-Shirt is a nod to high awareness and low visibility. Stay sharp. Stay shadowed.
