Compatibility, Size and Fit
Fit is the main practical check for this helmet. The two size ranges overlap, so the best choice depends on the exact circumference of the rider’s head and how the helmet sits once adjusted. Measure carefully before selecting a size, then use the one-handed adjustment to fine-tune the fit.
