The matt-finish Khimera helmet features a completely innovative aerodynamic design. A revolutionary ventilation system ensures optimal air flow that is adjustable through two separate ports: one on the front of the helmet which controls the anti-fog feature for the mask lens, and a second port on the back which vents the warm air generated by physical activity. These technical features, together with the quick-drying Soft Wind liner, offer exceptional comfort in even the harshest weather conditions. The patented Click-in System means that the liner can be easily removed and washed.
