Mythology rash guard: Poseidon Earth-Shaker for BJJ and grappling
The buying guide in 6 photos. Tap a photo, the answer opens below.

01Why choose a mythology rash guard?
Poseidon is more than a god of the sea: the Greeks first called him the Earth-Shaker, the force that makes the ground tremble with a 3-pointed trident. He stands among the 12 gods of Olympus, beside Zeus and Hades, in a 3-way division of the sky, sea, and underworld. That dual nature, calm at first glance and heavy underneath, speaks directly to grappling: stay composed until the moment you shift the opponent's balance.

Stone gray and bronze engraving create a heavy, controlled look without excess, far from loud colors. It suits pressure players who win through position rather than speed: committed takedowns, dominant top control, stability over explosiveness. In IBJJF no-gi, the rules require a black, white, or belt-color top, so keep this model for the gym and open mat, where color stays unrestricted.

03Short sleeve
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.
