📏 How to measure 

• Use a soft tape (or string)
• Measure around your head where the hat sits
  (roughly mid-forehead, just above ears)
• Keep it snug, not tight

Fit tips 

• If you’re between sizes → go up (you can pad down)
• Resistol tends to run long oval, so it suits narrower head shapes well
• Sizes increase in 1/8 increments, so small differences matter
