Classic Design Meets Modern Technology. The Cavalry 2 is a cutting edge smart helmet that blends classic half helmet styling with modern communication technology. The composite fiberglass shell and EPS lining provide protection and comfort, while the integrated communication system, speakers, and microphone keep the rider connected when they're on two wheels. The Cavalry 2 is the pinnacle of DOT certified half helmet protection, that is integrated with the latest innovations in communication technology. Cavalry 2 Smart half helmet features a new robust form of self-healing wireless communication. Mesh Intercom™ technology allows users to pair with the touch of a single button, enjoying an extremely robust and flexible connection. When a user in a group falls out of range, the rest of the group remains seamlessly connected while the Cavalry 2 intelligently searches for the lost connection and reconnects automatically once the user is back in range.
