Caps for Larger Heads

Wrap a tape measure (or a piece of string you then measure) around your head just above your eyebrows and ears, keeping it snug but not tight. If that comes in above roughly 58-60cm, hats for big heads will sit better than a standard running cap.

A cap that's genuinely too small leaves a red mark or ache across your forehead after a run, and can feel perched rather than seated. If you're adjusting the back strap to its limit and it's still tight, it's time to size up.

Yes, a larger-fit cap isn't just a fixed bigger size, it has more room through the crown and circumference, then the same adjustable rear strap so you can still fine-tune the fit. That's the whole point of hats for big heads done properly.

No, a larger-fit cap is proportioned for a bigger head, not just stretched. The crown depth and panel shaping scale with the size, so it sits the same way a standard cap sits on a standard head.
