How to measure to get your size
Please use a soft measure to measure around your head just above the ears and eyebrows.nStart approx. 2cm above your eyebrows, keeping the tape above your ears and around the back of your head at the largest point.
Helmet linings do compress, so if your helmet is slightly tight to begin with, this is quite normal.
