Product FEATURES
20-Vent Cycling Airflow System
Designed for cycling helmets, the 20-vent airflow system channels fresh air through the helmet to dissipate heat quickly and keep your head cool and dry.
Riding doesn’t wait.
Designed for a new era of cycling, this helmet perfectly adapts to every ride — delivering comfort, control, and protection whether in competition or everyday riding.
PC + EPS Impact Protection
Our advanced molding technology allows the polycarbonate (PC) outer shell to be directly cast onto expandable polystyrene (EPS) impact-absorbing foam during the molding stage. This triple-structure design creates an exceptionally rigid, lightweight, and impact-resistant helmet. The combination of EPS foam, PC shell, and exoskeleton structure effectively resists mechanical forces from impacts and dissipates energy, reducing the transfer of force to the wearer’s head.
Ionic+ Plant-Based Lining
Antibacterial surface fabric reduces odors, while high-density foam and silicone padding provide comfort and impact absorption. It minimizes sweat buildup, enhances airflow, and prevents unpleasant smells, ensuring maximum comfort and performance during long rides.
Lighter than ever.
A new standard begins.
At just 240g,this ultra-lightweight helmet is designed to disappear once you start riding.
Built to reduce fatigue without compromising safety, it delivers effortless comfort, efficient ventilation, and reliable protection
— setting a new benchmark for everyday performance on the road.
