Sublimated graphics won't fade or peel as you roll or wash your rash guard.

United StatesI got a gi, rash guard, and shorts. The shorts and gi are amazing. The rash guard is a 2x and it fits very small. I fit in most other 2x rash guards. The gi is so nice and the shorts are so comfortable. Top notch gear I will for sure buy more gear from BJJ Gold.
