How to measure the head circumference ? 
Use a measurement ribbon and place it about 1 cm above the eyebrows and ears.
If you do not have a seamstress gauge, use a simple ribbon or wire and measure it later.

If the measurement falls into two sizes, we advise you to choose the largest one to get more comfort,

and a too-tight hat can actually cause headaches.

We offer 2 cork strips with the hat, so you can always adjust the size if necessary.
