Kask Protone Icon OffRoad Gravel Cycling Helmet



Adult Road Cycling Helmet

The Kask Protone uses InMold Construction. This means that the polycarbonate shell is bonded to an EPS foam body. This is then secured over a frame, which allows the shell to absorb impact while keeping the structural integrity of the helmet. The Protone is secured with Kask's Octo Fit Cradle that adjusts to personalize the fit. The ECO chinstrap has antiodor properties. Not merely a shell to keep your head intact, the Protone is also an essential aerodynamic accessory.
