To determine your exact cap size, use a tape measure around your head where the sweatband rests.

Use the chart to convert the results to determine the exact size cap fit.

For in-between sizes, you will probably want to round up.

M/L sizing has been changed to "One Size - Stretch" or "OSS"

Please note: "OSFA" (One Size Fits All) and "OSS" are not the same.

Measurements are given in centimeters "cm" and in inches "in."
