TO DETERMINE HAT SIZE, measure around your head just above the ears and eyebrows.

Take this dimension in inches and divide by 3.14. This will give your hat size.

EXAMPLE:

For a head measuring 23.5 inches -
dividing 23.5 by 3.14 yields 7.48 -
7.48 equates to a 7-1/2 hat size.

See chart below to convert from hat size
to helmet size.
