The Reebok 9k Rib Pad has been designed for box lacrosse but is flexiable enough for field lacrosse. The 9k Rib Pad has a hard exterior material to better withstand the physical play from lacrosse. The multiple flex points in the pad allow for a snug fit. The pad stays tight to the players body with two adjustable front straps. The mesh shoulder straps are well ventilated and allow for the players body to stay dry.
