The internal structure has been redesigned to offer greater safety. The seamless technology that joins the upper and lower parts of the shell provides an elegant, refined look as well as aerodynamic advantages.

The new OCTOFIT+ adjustment system optimizes comfort and helmet stability, while the extended vertical stabilizer at the back of the head offers ergonomic neck support, ensuring better balance and a customizable fit. The adjustment dial, covered with a special rubber, is larger and provides improved grip, and the reflective insert on the rear of the helmet enhances safety on the road.

The inner padding, made from CoolMax® fabric, is comfortable, quick‑drying, removable and washable. As with all KASK helmets, Protone Icon has been developed in accordance with the KASK ROTATIONAL IMPACT WG11 TEST protocol, an objective and scientific approach to measuring helmet performance against rotational impacts.
