Measurements are required for your custom unit to fit properly. Incorrect measurements can result in an improper fit of your unit. If that is the case, the custom unit is still FINAL SALE and there will be NO REFUND for measurement mistakes. 

Basic Sizing:
Small (21-21.5 in. Circumference)
Medium (22-22.5 in. Circumference)
Large (23-23.5 in. Circumference)

Refer to the chart below and referenced video to assist you in measuring your head. Please ensure your hair is as flat as possible to reduce bulkiness for more accurate measurements.
