How to measure your head for the best Hat Size.
Wrap a tape measure around your head, starting at the back where it’s widest (just over the bump at the back of your skull).
Bring the tape around to the front, positioning it roughly 5mm above your ears. It should rest comfortably across your forehead or just above your eyebrows—wherever you’d prefer your hat to sit.
Make sure the tape feels just right—not too tight, not too loose. This is how your hat will sit once it’s on. Not sure which size? If you’re in between, it’s best to size up.
All our hats feature an adjustable strap, letting you fine-tune the fit for maximum comfort.
