The KASK Protone Icon is a premium performance cycling helmet engineered to balance aerodynamics, comfort, stability, and protection across road, gravel, cyclocross, and cross-country mountain biking.
Redesigned throughout, the Protone Icon features an internal strengthening frame engineered for greater mechanical strength and structural compactness. KASK’s seamless construction joins the upper and lower portions of the shell for a refined profile while helping improve aerodynamic performance.
The OCTOFIT+ adjustment system provides a secure, personalized fit with an oversized rubber-coated adjustment dial for improved grip. A redesigned vertical stabilizer at the rear provides greater stability and ergonomic support at the nape of the neck, helping the helmet remain comfortably positioned throughout demanding rides.
Inside, removable and washable CoolMax® padding provides a soft, quick-drying surface to help manage moisture and maintain comfort. The helmet is finished with KASK’s signature faux-leather chinstrap, designed to be comfortable against the skin and easy to clean. A reflective rear insert adds visibility in lower-light riding conditions.
The Protone Icon is developed in accordance with the KASK Rotational Impact WG11 Test protocol and meets the CPSC 1203 bicycle helmet standard.
