The revolutionary design of Kimera's ventilation system guarantees excellent adjustable airflow, together with a separate port for goggle anti-fog and a separate port for hot air outflow. The combination of a ventilation system and quick-dry fabric liner allows for greater comfort even in the most demanding conditions. The liner can be easily removed and washed thanks to the proprietary click-in system. It also features the patented Fit-System, a self-adjusting element that ensures maximum stability.
