We recently updated our size codes to be more intuitive, learn more here. Each size code is the combination of a Width Number and a Letter Code. Combine those to get your FitCode. For example, your Width Number could be 53 and your Length Letter is G. Therefore your FitCode is 53G. There are 9 total widths to choose from & 10 different lengths. When you’re using the FitKit, you’ll see those codes directly on the tool. Or you can simply put in your length and circumference measurements here, and the online tool will tell you your MyONE size code. The size codes also keep your specific length and width private.
