The Protone Icon helmet from Kask is a new victory icon in the world of road cycling. It boasts the latest technological advancements in safety, ventilation, and aerodynamics, making it a true icon of road cycling. The Protone Icon takes its design from KASK's winning Protone helmet and enhances it in every way possible. The internal frame has been redesigned to provide the user with increased safety. The technology without seams unites the inferior and superior parts of the helmet, giving it a refined and elegant appearance as well as improved aerodynamics. The new OCTOFIT adjustment system optimizes comfort and stability for the helmet. A vertical stabilizer at the nape of the neck provides ergonomic support for the neck, offering better balance and a personalized fit. The large dial at the back of the helmet, covered in a special rubber, increases grip with the fingers and a reflective piece at the back enhances user safety.
