THE STORY:
THE FIRE OF THE THIRTEENTH
As winter fog clung to the Rubicon, the fate of Rome rested upon the Legio XIII Gemina. Forged in loyalty and sharpened in the fires of the Gallic Wars, this was the unit Julius Caesar trusted to shatter the Republic’s peace. This Black Edition jersey channels the shadow of the empire, featuring Pompeian red side panels that echo the blood and glory of Rome’s decisive conquests. The front bears the lion insignia, the king of beasts and emblem of unyielding will, while the back carries the Roman numeral XIII and Caesar’s immortal command to move forward where the gods call.
