Delivering on all the key prerequisites for a great helmet, the Lazer Century is comfortable, aerodynamic, visible and, most importantly, it offers exceptional protection. The innovative Twist Cap mechanism lets you alternate between a fully ventilated helmet or aero helmet, on the fly, with a simple twist-of-hand action. If it's hot you can maximise airflow and cooling to your head and then close off parts of the ventilation to save watts and ride faster. At the rear, a rechargeable LED light is integrated into the construction for an extra touch of safety and internal channels actively control and direct airflow around and through the helmet.
