HX HELMET EXTENSION: These jaw guards are designed to fit HX batting helmets. Connect them to any HX Batting Helmet for additional jaw coverage. REVERSIBLE: Made with a patent-pending double-lock design that makes them reversible, allowing them to be switched between the left and right sides of the helmet. EASY INSTALLATION: Hardware is included with the jaw guard and no drilling is required, so installation is quick and easy. NOCSAE STANDARD: HX helmets meet NOCSAE standard; attachment of the jaw guard does not affect the helmet’s ability to meet NOCSAE standard. COLOR OPTIONS: Comes in colors to match most HX helmets. Matte-finished for a premium surface feel.
