Q: How do I work out my size for a Jacaru hat?
By using a soft measuring tape, measure the circumference of your head just above your ears and refer to the size-charts. The link to the size chart is above the FAQ tab under More Information list on the bottom of this page. If you are in between sizes go up to the larger size. You can always place a sweatband/size reducer (purchase from our accessories) in the front and or back of the hat. If you have any difficulty determining your size, please send us the measurements and we can recommend a size to fit.
