Formula CP DBK Helmet. The Formula CP DBK Helmet combines lightweight construction with advanced impact protection. Featuring RHEON Impact Energy Cells, multi-density EPS, and True Functional Ventilation, it's built for serious riders who demand safety, comfort, and performance. This helmet is the result of a dynamic collaboration between FLY Racing and DBK, blending elite-level design with bold, rider-driven style. Polycarbonate alloy shell construction produces an extremely lightweight shell with excellent penetration resistance. Impact Energy Cells made of RHEON maximize absorption of low-speed linear and rotational impacts. Multi-density EPS provides a progressive response to low and high-speed impacts. Expanded volume EPS adds more impact-absorbing material in critical zones. EPS chin bar enhances impact mitigation and damage resistance. Clavicle shell relief zone helps reduce clavicle injuries.
