The oversized 180 across the back, PERFORMANCE beneath it, and the creed under that: THE GRIND TODAY. THE GLORY TOMORROW. The boldest piece in the line.
Worn in fight camps from Vegas to Miami by fighters who put the work in — then cut loose and light enough to live in outside the gym. Sleeveless, relaxed through the body, with wide low-cut armholes so nothing pins your shoulders when you move.
