How to Find Your Size
Wrap a thin, non-stretchy strip of paper around your finger and mark where it overlaps.
Straighten and measure the length in millimeters.
Match your measurement to the perimeter in our size chart to find your perfect fit.
Tip: Measure at the end of the day when fingers are slightly larger for the best fit.
