The Protone weighs just 215g & uses a 3D Dry padding with a multi-layer open cell construction process to give a more comfortable ride. It has removable & washable inner padding¸ made from Cool Max® fabrics & 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 & 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
