How To Determine Your Cap Size
It is a good idea to have someone to help you with measuring. Put your index finger on your temple. This is to ensure that the cap will not be too tight. Place the tape measure above your eyebrows and above your ears and keep the tape measure as level as possible.
Make sure that the tape measure at the back of your head stays at the widest point of the skull during the measurement. The tape measure should not slip too low towards the neck or too high towards the top of the head, but stay level as shown in the picture. The tape measure should be held quite firmly to make sure that the tape is not too loose. One finger between the tape measure ensures the tape is not too tight. Please tell us the measurement indicated on the tape measure.
