The Aurelius rash guard pulls from stoic ideals: discipline, composure, and control when things get chaotic. Designed in collaboration with Abraham La Montagne, this is his official pro model. Support Abe by picking up his official kit.
Built on our Foundation Rash Guard base model, it’s made for hard rounds and long sessions. Features include buttery smooth flatlock stitching that won’t irritate, a slightly extended cut that stays in place while you roll, mesh underarm panels for ventilation, and fully sublimated graphics that won’t fade or peel.
