Sizes
If you're between sizes, choose the bigger size.Choosing the right-sized helmet and getting the fit right is essential. For kids, never buy a helmet that is too big on the assumption that they will grow.M: 20.9” – 22.8”L: 22” – 24”
Adjustment
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.
