The All Star MVP2300SP Catcher's Helmet features a molded reinforced ABS plastic shell. This catchers helmet includes a heat treated steel facemask. The I-Bar Vision mask design improves the sight line for a 40% greater field of view and protects the face from ball impact. The dual density foam liner adds extra protection. The chin pad is contoured molded foam with a vinyl outer surface and a moisture managing poly cloth inner surface. The Ultra Cool ventilation system has 3D fabric mesh that pulls in cool air and expels heat and moisture to keep athletes comfortably cool. Unlike 2D synthetic cloth that passively wicks moisture, the patent pending 3D construction transports moisture away and promotes the circulation of cool air around the player's head. This catcher's helmet is Aegis microbe shield treated to provide protection against bacteria, fungus and related odors.
