Construction In-Mold Construction – In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets. TPU Injected Brim Ventilation Passive Aggressive Venting System – Clean linear exterior vents combine with ergonomic interior channeling create optimal airflow and temperature regulation. This auto-venting technology manages airflow and temperature regardless of activity level. Stack Ventilation – Stack Ventilation was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration. Fit In Form™ 2 Fit System – The In Form 2 Fit System is lighter and lower profile than the original, making it even easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6 cm of adjustment plus enhanced stability.
