The combination of Zonal Koroyd® and Mips® help to absorb impacts and rotational forces so you can focus on the ride. Our VaporFit™ system lets you adjust the helmet on the fly with the turn of a dial, and the Mips® layer is integrated with the fit system for a snug, cohesive fit that feels great all day. Nineteen integrated vents with internal air channels maximize airflow to keep you cool and your glasses fog-free through any level of effort. Little details like integrated sunglasses storage and a low-profile strap divider make a difference in convenience and comfort on the bike.
