Kask Protone Icon offers claimed improved fit, ventilation, and aerodynamics

Latest version of the Protone weighs a claimed 230 in a European medium.

Don't miss a moment from Paris-Roubaix and Unbound Gravel, to the Giro d’Italia, Tour de France, Vuelta a España, and everything in between when you join Outside+.

Kask’s popular Protone helmet just got an overhaul internally and externally with the new Protone Icon, available today for $299.

The Kask Protone has been visible in the WorldTour peloton for years, worn to victory at five Tours de France, two Vueltas a España, and four Olympic events.

The new Protone Icon gets better ventilation, aerodynamics, and fit, Kask claims.

Kask’s new OCTOFIT+ adjustment structure supports a broader area of the head, and a larger, rubber-coated rotation dial makes adjustments easier, Kask claims. The OCTOFIT+ system is ponytail-friendly, as well.

Kask uses CoolMax fabric for the liner, which is removable and washable.

Along with Lazer and members of MIPS, Kask has a representative in the WG11, a working group that advises the helmet technical committee at European Committee for Standardization (CEN) about testing standards. This WG11 group has been laboring to establish helmet testing protocols above and beyond what various governmental organizations like the CPSC or CEN require.

Somewhat confusingly, Kask has its own new safety standard called the WG11 that is in no way related to the WG11. Kask established its own test following a motorcycle helmet testing protocol, and branded it WG11.

Kask claimed the Protone Icon weighs 230g in size Medium in the European version. The U.S. version will likely be a bit heavier.

The helmet comes in 10 colors.
