Greatness redefined
The new synonym for victory? Protone Icon. The helmet benefits from the latest technological advances in safety, ventilation, and aerodynamics, making it an icon of road cycling. The Protone Icon's design draws inspiration from the Protone, KASK's winning helmet, improving it in every single aspect.

TECHNICAL DESCRIPTION
The internal structure has been redefined for greater safety. The seamless technology that joins the upper and lower parts of the shell provides a sleek and refined look, as well as aerodynamic advantages. The new OCTOFIT+ adjustment system optimizes the helmet's comfort and stability, while the vertical stabilizer along the nape of the neck provides ergonomic support for the neck, allowing for better balance and a customizable fit. The adjustment wheel, covered in a special rubber, is wider and offers greater grip for the fingers, and the reflective insert on the back of the helmet helps increase safety on the road. The internal liner, made of CoolMax® fabric, is comfortable, quick-drying, removable and washable. As is standard with all KASK helmets, the Protone Icon was developed in accordance with the KASK ROTATIONAL IMPACT WG11 TEST protocol, which is an objective and scientific approach to measuring a helmet's performance in response to rotational impacts.

WHAT'S MY SIZE?
HOW DO I CHOOSE THE CORRECT SIZE HELMET?
The choice of helmet depends on its technical features and the performance it ensures, as well as on comfort and design.

Tips for choosing a helmet:
1. First, wear the helmet for a few minutes to check if it fits well or if it causes discomfort anywhere on your head.
2. After wearing it, try simulating some movements to check its comfort.
3. Once fastened, the helmet should feel comfortable but not move.
4. The strap and buckle must be fastened without impeding the neck's movement.
5. Always check the safety and comfort of the helmet to help you choose the best one!

KASK helmets are sized based on your head circumference. You can use a tape measure: place it just above your ears and note the measurement in centimeters.
