If you are between sizes, choose the larger size.
Choosing the right size helmet and getting the fit right is essential. For children, never buy a helmet that is too big on the assumption that they will grow.


For maximum protection, the helmet should be in close contact with your head and the fastening system must always be correctly adjusted, without being too tight around your forehead. When the straps are properly adjusted the helmet should not slide forward, back, or sideways. For this reason there are several sizes available. We recommend that you try on different sizes to find the best fit.


Size S: 240g
Size M: 250g
Size L: 324 g
