The Protone is probably the most advanced helmet in the current Kask programme. Technically innovative and with a unique look. Developed in collaboration with the successful Team Sky, the Protone cycling helmet sets standards in terms of ventilation, heat dissipation and aerodynamics. Thanks to the large openings, the contact surface to the head is greatly reduced. At the same time, an internal substructure holds the helmet together in the event of a fall.
