The next generation of TT helmets is here. A true revolution in aerodynamic helmets, designed to be faster than the competition. The P-09 helmet utilizes the innovative technology of the Vorttice helmet with improved aerodynamics, improved ventilation, and an improved lens system. The frontal surface is reduced to a minimum, making the helmet more compact. The inferior part of the tail is reversed for a better airflow at the shoulders, and a Speed Port allows air that enters at the front of the helmet to exit through vents behind the ears and release any pressure. A better vent position combined with additional and deeper evacuation channels allow a better airflow for an improved ventilation. The improved lens system includes a visor that lifts up for a fast and easy transition, and that can be easily removed using just one hand.
