Due to the broad ranges of textiles and sizing systems utilized in our hats, each fit slightly different. See individual hat sizing ranges on their product pages.
HAT QUICK FIT TIPS:
98% of adults fit easily in our 2 sizes. To measure your head, circle the crown of your head with a string or dental floss (above eyebrows and ears.) Use a ruler to measure the string and compare to the above chart. Upon receiving your hat, loosen or tighten the sizing tape for a custom fit. Fit the hat slightly above eyebrows and ears to allow front and peripheral vision. Crown fabric should remain loose.
