Helmet House's HJC AC-2 LE offers the motor officer a traditional half-shell design with a multitude of features in a high-quality, high-value helmet. The AC-2 LE uses a lightweight, fiberglass and Spectra shell construction. Featuring a triple intake ventilation system combined with a channeled liner and two rear venturi exhaust vents, the AC-2 LE offers increased flow-through ventilation, keeping the officer's head cooler on the job. A removable and washable Nylex inner liner, plus a removable zip-off neck curtain, offer added protection in colder climates. Other features include a drop-down fiberglass section for safe and simple communication system installations, and two sets of speaker communication pockets one in the removable neck curtain and one attached permanently to the nylon retention strap.
