Fit & Comfort Tips
- Hat fit is personal — choose what feels most comfortable for you.
- A tighter fit is useful for active days or windy weather.
- For long wear (4+ hours), a slightly looser fit may feel better.
- Hat shape can change how the size feels — always check this guide before choosing.
- If between sizes, choose the larger and adjust using a small sizing insert.
