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.
- OS = One Size.
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 (2.5cm approx. above your eyebrows).
