Size Guide for AF Masks
In order to choose the correct size of this mask, measure your vertical head girth (A) around the head / face starting underneath the chin, up one side of the head just through one ear, over the top of the head and down the other side just through the other ear, ending at the chin to make a complete circle. Measurement should be done in cm.
