CORRECT HELMET SIZING
Each helmet model has small differences in its shape that ultimately affect the fit. For this reason, it is essential to test a helmet before buying it. Test whether it sits on your head properly by putting on the helmet and moving your head to the left and right, as well as up and down while holding the helmet firmly with both hands. If your head can move too freely within the helmet, we recommend that you try a smaller size. If you feel local pressure points, then choose a helmet that is one size larger, or perhaps try on a different model.
(H) HEAD
Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement.
