Hats and Headwear

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 (about 3cm above your eyebrows).
