Stack Vent™ - Stack Vent™ aligns the center top vent of the helmet with the center vent of your goggles to help eliminate fogging while maintaining total helmet and goggle integration.
Super Cool™ Vents - 12 Super Cool™ vents pull cool, fresh air into the helmet while pushing heat and stale air out.
Thermostat Control - Thermostat™ ventilation control allows you to custom tune the airflow through your helmet instantly with a simple, low profile button on the outside of the helmet.
In Form™ Fit System - An ergo-friendly dial at the base of the helmet provides up to 6 cm of adjustment and can be easily adjusted with gloves on. The vertical tuning feature accommodates different goggles and head shapes for a gap-free fit.
