The Protone is arguably the most advanced helmet in the current Kask lineup. Technically innovative and featuring a unique look, the Protone cycling helmet sets standards in ventilation, heat dissipation, and aerodynamics, developed in collaboration with the successful Team Sky. Thanks to the large openings, the contact area with the head is significantly reduced. At the same time, an internal substructure keeps the helmet intact in the event of a fall.
