The CCM Tacks XF Pro Youth Shoulder Pads feature elite-level protection powered by D3O foam for extra impact absorption. An important area of the body, the sternum, is built with compressed-molded EVA foam and D3O, providing the ultimate combination to protect the front of the body from stray pucks or accidental collisions. D3O specifically is made to absorb and dissipate impact energy away from the body.
