The Kilauea is a great answer for those who want a more aerodynamic road helmet, without losing the Catlike ventilation. The Kilauea uses only 24 larger vents (10 front, 14 rear) to channel air around your head. The design pulls more air from the rear, allowing from better aero results. This helmet is was developed with a comfortable overall fit, as well as the MIPS Evolve system* for increased safety rotational impact protection. This helmet is superlight, weighing in at only 240g for a medium, but does not lack in structural strength using a Aramid Roll Cage. This feature acts as a ``skeleton`` to dissipate the energy of an impact evenly throughout the helmet, as well as hold it together in a crash. This top performance helmet will make you fast, as well as keep you cool! *The Black and White models will not be available until MIPS is available in them due to Catlike going through the process of updating their lineup.
