Kask leads the pack when it comes to helmets. Still 100% made in Italy, with an emphasis speed, comfort, and, most importantly, safety. The Protone has long been the standard when it comes to hybrid aero-road helmets. Weighing in at only 215 grams, this helmet features the lowest wind drag, and fastest heat dissipation compared to any other ventilated helmet on the market.

Made with multi in-molding technology that fuses a polycarbonate shell on top, at the base ring, and at the back of the helmet, to an EPS foam body, the Protone also features an internal plastic sub-structure that reinforces the top area for maximum impact protection. This strengthened frame further reduces the risk of impact breaking the shell.

All this tech kicks in when you fall off the bike, but what about while you're riding? An extensive amount of wind-tunnel testing has helped Kask produce a shape that provides perfectly smooth airflow over the helmet, whether you're in the drops, or virtually any other position.

Temperature management plays a big role in comfort. The Protone's specially designed intake/exhaust vents and channels, ensure you get the best of both aerodynamics, and ventilation. Coupled with Coolmax pads for optimal moisture management and evaporation, with an anti-microbial treatment making them resistant to bacteria and odors. Plus, once they wear out, they're easy to remove and replace with original Kask replacement pads. The floating Octo-Fit retention system fully adjusts fit with a simple twist of a dial at the rear, and the soft ECO leather strap sits comfortably beneath your chin.
