The Kask Men's Protone Bike Helmet helps you stay safe while having your most comfortable ride experience ever. This helmet has removable and washable inner padding made from CoolMax® fabrics, and its inner padding fabric has been treated using the Sanitized® antimicrobial process. Kask has also continued to use its Multi In-Moulding Technology to create a polycarbonate cover for the top, base ring and the back of the helmet's shell. The Protone features an inner polystyrene cap via In-Moulding Technology to improve the shell's shock absorption while its strengthened frame further reduces the risk of a shock breaking the shell.
