A blast-resistant helmet may be constructed with an aramid core, some type of molded protective outer layer and a suspension harness for comfort. Helmets have a clear, anti-ballistic visor, and some have built-in headphones and a microphone, as well as the ability to transmit signals. These specialized helmets may have an internally powered ventilation system that cools the wearer and de-mists the visor. There may also be brackets where the technician can mount a hands-free video camera or light.
