Measure head circumference in inches, then match it to the closest row below to find the right shako, helmet, or hat size before you order.
Wrap a soft tape measure around the largest part of the head — just above the ears and eyebrows — and round to the nearest 1/8". Match that number to the chart to get a US hat size and shako size.
