Product Review

Developed in collaboration with team sky, the Kask protone road helmet is super-lightweight, highly ventilated and aerodynamic, plus its skull-hugging, low-profile design feels like it was specially Fitted for your head. It's been wind-tunnel tested to maintain streamlined performance and ventilation in virtually any riding position; even if you move your head, it'll remain consistent. It's also been designed using computational fluid dynamics software to attain one of the lowest drag coefficients of any ventilated helmet.
