Fit Tips

If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

How To Measure

Measure the circumference of your head using a tape measure. Wrap it around your head at the point where the hat will sit (3cm approx. above your eyebrows).
