Technical details and features

At the heart of the Protone Icon is the redesigned inner frame, which mechanically reinforces the helmet's structure for added stability. A seamless connection between the lower and upper shell sections gives the helmet a refined, elegant look with improved aerodynamics, while the new OCTOFIT+ adjustment system optimizes comfort and stability, and a vertical stabilizer at the neck provides ergonomic support and a personalized fit. The large adjustment dial features special rubber coating, noticeably improving grip, while a reflective insert at the back offers the wearer additional safety. Comfort is provided by the CoolMax® inner padding, which is not only comfortable and quick-drying but also removable and washable. The chin strap made of synthetic leather rounds off the fit, making the helmet comfortable to wear even on longer rides.

Areas of use and benefits

The Protone Icon is designed as a road helmet, but it also proves its strengths off the road. Thanks to its versatility, it's equally suited for fast road rides, technical gravel routes, as well as cyclocross and MTB cross-country use. The shell's aerodynamics ensure that airflow is directed around the head with minimal resistance, which is especially noticeable during high-speed rides and races. At the same time, the well-thought-out ventilation concept combined with the CoolMax® material ensures that heat and moisture are efficiently transported away. For riders looking for a helmet for multiple disciplines, the Protone Icon offers a practical solution without having to buy several specialized helmets.

Safety to KASK standard

Like all helmets from KASK, the Protone Icon was developed according to the brand's own test protocol for rotational impact. This standard is an objective, scientific approach to measuring helmet performance across various types of rotational impact. In addition to the internal testing procedure, the helmet meets the European standard CE / UKCA - EN 1078, which is the legal minimum requirement for bicycle helmets in Europe. This combination of proprietary testing approach and official certification makes the Protone Icon a well-considered choice for safety-conscious riders. The matte finish of the outer shell also provides a subtle, timeless look that pairs well with different bike setups.
