The elements are in perfect equilibrium: performance, aerodynamics and safety. The design leaves you in no doubt: Protone Icon is KASK's new classic, an exceptional helmet for road, gravel, cyclocross and MTB cross-country. Every aspect has been redesigned to push performance to the limits.


A redesigned internal frame gives the wearer greater safety. Seamless technology joins the lower and upper parts of the shell to give it a refined, elegant look and improved aerodynamics. The new OCTOFIT+ adjustment system optimizes the helmet's comfort and stability, while a vertical stabilizer across the nape of the neck provides ergonomic neck support and delivers enhanced balance and a customized fit. Its large rotation cap coated in a special rubber increases finger grip, and a reflective insert in the rear helps keep the helmet's wearer even safer. The internal lining is made of CoolMax® fabric which, as well as being comfortable and quick-drying, is also removable and washable. As is standard with all KASK helmets, the Protone Icon has been developed in accordance with the KASK ROTATIONAL IMPACT WG11 TEST protocol, an objective, scientific approach to measuring the helmet's performance against rotational impacts.

Finding your perfect fit
Discovering the ideal size for your KASK helmet is as easy as measuring the circumference of your head. Position a tape measure just above your ears. In the figure above, the dashed line shows the correct inclination.
