Protone Icon

$150 ~~$300~~ In stock

The new synonym for victory, the Protone Icon helmet features the latest technological advances in safety, ventilation, and aerodynamics to make it an icon of road cycling. The Protone Icon takes its design from KASK’s winning Protone helmet and has improved upon it in every way possible.

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.

The aero shaping is subtle but real—I can feel the difference holding my line in a stiff crosswind. It's also lighter on my head than my old lid, which makes long climbs noticeably less annoying.

The ventilation on this is genuinely impressive—even on a hot climb my head stays cool, and the fit feels locked-in without any pressure points. It’s light enough that I forget it’s there, and the aero shaping gives me a bit more confidence in fast descents. Exactly what I wanted in a road helmet.
