The most advanced catcher's gear available, Wilson ProMOTION Catcher's Gear utilizes isoBLOX™ impact diffusing technology to create ultra-light and flexible gear which means you are more mobile behind the plate. The ProMOTION chest protector has been ergonomically designed to move with the unique motions of a catcher -whether blocking the plate or backing up first. It provides fitted, flexible protection without adding bulk or stiffness. isoBLOX is an advanced impact-blocking material that is exclusive to Wilson baseball and softball equipment. This innovation has been engineered and lab tested to offer exceptional impact resistance without impacting ball rebound or compromising flexibility. As a result, ProMOTION Catcher's Gear provides superior protection that moves, bends, and flexes right along with the athlete.
