Size & Fit Guide

All Wallaroo Hats have an internal drawstring to fit the hat to your head (the women's Aqua Hat is the only exception - it stretches to fit). Be sure to choose a hat that is the same circumference as or smaller than your head size. If your head size is bigger than the listed hat sizes, the hat will not be comfortable. Please contact customer service at (303) 494-5949 if you have any questions.


How to measure your head size:

  • Find a piece of string.
  • Wrap the string around your head, positioned above your ears and eyebrows — image that the hat is sitting where you're holding the string.
  • Find the end point by pinching the string where it wraps back around to meet at the starting point.
  • Measure the length of the string from starting point to end point against a ruler and note the measurement.
  • Look for the corresponding measurement on the below chart to find your head size.
