Besides a sinister looking, performance infused, and lightweight carbon fiber helmet, you’ll find the latest in communication technology nestled inside. The integrated Bluetooth® headset and microphone have been smartly designed as part of the helmet’s internal padding and allows you to communicate with your passenger for up to 12-hours on a single charge. Riding in a group? Sync with one to four riders with an up to one mile range. The result is a helmet that offers all the protection you need with amazing looks and comfort without the wires, hassle, or bulk of traditional external mounted communicators.
