To check your head circumference, simply use a tape measurer and wrap it around your head firmly. If you don’t have a tape measurer, use a string or piece of floss then measure with a ruler.
Our regular silk eye mask comes with an elasticated strap, and will comfortably fit head sizes 54cm-56cm.
However, if your head is larger, or smaller, we recommend choosing our black adjustable eye mask which can fit up to 60cm head circumference.
