The K1 Pro is a race-ready, multi-use, full-feature helmet with superior ventilation, aero styling, and an aggressive chin bar design complete with a front chin spoiler (duckbill). Incorporating lightweight construction, excellent fit, and multiple ventilation options, the K1 Pro is perfect for open-wheel racers, closed-cockpit drivers, and karters who demand value, performance, and superior features. The K1 Pro can be used in an open-wheel configuration with an air intake piece (included) and in a closed-cockpit configuration with a forced air intake (sold separately).
