The Protone weighs just 215g and uses a 3D Dry padding with a multi-layer open cell construction process to give a more comfortable ride. It 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. This is joined to the inner polystyrene cap via KASK¡¦s In-Moulding Technology to improve the shell¡¦s shock absorption. Its strengthened frame further reduces the risk of a shock breaking the shell.
