The Protone weighs just 215g and uses 3D Dry padding with a multi-layer open cell construction process for a more comfortable ride. It has removable and washable interior padding, made from CoolMax® fabrics and its interior 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 rear of the helmet shell. This is joined to the polystyrene inner cap via KASK's In-Moulding technology to improve the shell's shock absorption. Its reinforced frame further reduces the risk of an impact breaking the shell.
