The Kask Protone Icon is the evolution of one of the most successful helmets in professional cycling. Worn by WorldTour champions in Grand Tours and one-day Classics, the Protone Icon combines aerodynamic efficiency with exceptional ventilation. The carefully shaped shell channels airflow through strategically placed vents, keeping you cool without sacrificing speed. The CoolMax lining wicks moisture away from the skin, while the OCTOFIT+ retention system provides tool-free micro-adjustment for a locked-in feel. A reflective insert at the rear enhances visibility during early morning or late evening rides. Certified to CE EN 1078 and WG11 for comprehensive head protection.
