durable material: made of high-performance pe, the shin plates display improved flexibility and durability without added weight. protective design: the cantilever system spreads the shock of impact and minimizes force transferred to the catcher’s shins. double knee protection: the “double knee” extra knee cap covers part of the upper leg, providing extended protection. built-in ventilation system: air flows through the built-in ventilation holes to prevent heat buildup and keep catchers cool. color options: choose between black, navy blue, royal blue, and scarlet red.
