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. 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.
