Helmet Measurement Method
Because the helmets are different in size, you need to choose the size that suits you. After measuring your
head circumference, you can select the right helmet size according to the circumference. If the helmet is too
loose or too tight, you can adjust it by turning the adjustment wheel until it is comfortable to wear, or try a
different size helmet.
The head circumference needs to be measured twice to get the maximum
value. The first measure, by using a soft measuring tape, is around the
hairline to the point that 2 cm (about 0.8 in) below the occipital bone. The
second measure is around the brow bone to the occipital bone.
Note: Due to different head shapes, the helmet may not match your head completely. If you feel uncomfortable
while wearing it, please select a different size.
