Men's Rash Guard

On the mat, your top takes everything: friction, grips and your opponent's sweat. A cotton T-shirt stretches, soaks up sweat and gives your opponent something to grab. A men's rash guard stays close to the body: it helps protect skin from mat burn, keeps loose fabric out of the way and can be washed after every session. 5 reasons to wear a rash guard.

The men's cut follows the shape of the shoulders and back: the fabric does not pull when you frame, and the hem stays beneath the waistband of your shorts.

For BJJ with a gi, wear it underneath your jacket at the gym: choose long sleeves to protect your arms from friction against the lapel and sleeves. In no gi and grappling, it replaces the jacket; both cuts are worn, and color matters in IBJJF competition. In MMA, short sleeves keep the shoulders free for striking and cage work. In wrestling, the top must stay tight to the body so there is nothing to grab: short sleeves here too.

Every design covers the whole back and wraps around the sides and sleeves, with no empty space.

In BJJ with the gi, choose long sleeves: they protect the arms from jacket friction and don't ride up during guard passes. In no-gi and grappling, both cuts work; short sleeves leave the shoulders freer. In MMA and wrestling, short sleeves are the most common choice.

In no-gi, IBJJF requires a black, white, or black-and-white base, with at least 10% in the belt colour. Check the dominant colour of the design against your tournament rules. At the club, on open mat, and in tournaments with no colour code, they work everywhere.
