First, measure your wrist. I recommend measuring in cm for accuracy and leaving 1-2 finger width gap.

Use the chart below to determine your size.

If between sizes, I recommend sizing up.

WRIST MEASUREMENT

SMALL <6.5 IN | < 15.25 CM

MEDIUM 6.5 - 7 IN | 15.25 - 17.75 CM

LARGE 7 - 7.5 IN | 17.75 - 19 CM

X-LARGE > 7.5 IN | > 19 CM
