Heads come in all sizes, and in a surprising variety of shapes. Although fitting pads make our helmets adaptable, and will usually conform to differences in shape with few adjustments, it is essential that the size be correct for the head. All heads are oval shaped and are longer front to back than side to side. If you know that your head is a longer oval or a rounder (shorter) oval, let us know.
To determine your helmet size, measure the circumference around your head, keeping the tape level and firm, across the temples and above the eyebrow ridges. If you do not have a tape measure you can use an string that does not stretch easily and then measure the string length. Measure three times for accuracy. Check the size chart given below. For in-between measurements use the next size up.
