As shown in the diagram above, measure from above your eyebrows to above your ears and around your head with the tape measure. Tighten the tape measure moderately to measure your head circumference. The size is approximate and can be determined by measuring 5mm to 10mm in front or behind the head circumference.
Advice from our staff
The N-PRO is made up of five structures, so it is thicker than previous head caps. It wraps around your head tightly, so it may feel a little smaller than previous head caps. If you are concerned about the size, we recommend choosing the larger size.
