The Helmet House HJC AC-2 LE offers the motor officer a traditional 1/2 shell design that utilizes a lightweight, fiberglass and Spectra shell construction. This rigid shell has a triple intake ventilation system combined with a channeled liner and two rear venturi exhaust vents. This helmet has a removable and washable Nylex inner liner, removable zip-off neck curtain, and a Nylex inner liner for added protection in colder climates. HJC's nylon strap retention band with a nape strap neatly secures the AC-2LE in place. The HJC AC-2 LE meets or exceeds DOT helmet standards.
