Fuji unleashes this striking MMA rash guard on the MMA world, showing off some amazing visual design talent. The visual effect of this rash guard is in a league all it’s own, with art inspired from “Japanese symbols, icons, and nature,” according to Fuji themselves. The fish featured on the front is called the Koi, and it acts as a symbol of a person’s will to succeed over all obstacles. This is a very fitting idea for a piece of gear used in mixed martial arts training. The fabric is non-irritating and wicks moisture, keeping you comfortable and dry during workouts.
