The Jetstream TT helmet offers a great combination of speed and safety elements. The polycarbonate material creates a lightweight aerodynamic helmet that also has high impact resistance. Equipped with both MIPS and Koroyd layers, this helmet will reduce impact to the head during a crash. With five air vents, optimal airflow is created so that you can stay up to speed on race day. A low profile y-strap divider is also in place to help with aerodynamics. The Jetstream also features a magnetic visor for easy removal to switch between two lenses, a basic clear lens and the color enhancing ChromaPop.
