All-Star Youth System 7 Catcher's Helmet The helmet features an I-BAR VISION steel cage, a high impact resistant ABS plastic shell with increased forehead thickness, a backplate designed to keep the snaps on, and a breathable machine washable 3D mesh padding liner. The bars on the cage around the eye openings are flatter for increased range of view and to make the bars stronger. Instead of using a round steel wire, the I-BAR VISION cages utilize a flat bar which is comparable to an I-Beam used in building construction.
