If your head measurement falls at the end of the size and you usually wear a size L cap then please choose size L.
Directions for Correct sizing
Place a string or fabric tape measure around your head about 3-4 mm (1/8") above your ear, across the middle of your forehead, completely encircling your head. Hold the tape firmly, but not too tightly. If your head measurement falls at the end of size (for example, 60cm), choose the smaller size.
