The internal structure has been redefined to offer greater security. The seamless technology that combines the top and bottom of the cap gives an elegant and refined look, as well as aerodynamic advantages. The new OCTOFIT+ adjustment system acts optimally on the comfort and stability of the helmet, while the vertical stabilizer along the neck provides ergonomic support for the neck, allowing a better balance and customizable fit. The adjustment wheel, covered by a special rubber, is wider and offers greater grip for the fingers, and the reflective insert on the back of the helmet contributes to increasing road safety. The inner coating, made with CoolMax® fabric, is comfortable, fast drying, removable and washable. As usual with all helmets KASK, Protone Icon was developed in accordance with the protocol KASK ROTATIONAL IMPACT WG11 TEST, which is an objective and scientific approach to measuring helmet performance compared to rotational impacts.
