Figuring out your wrist measurement:
Wrap a string loosely around your wrist at the wrist bone, e.g. dental floss. Add 1" to your measurement and choose your size and color from the drop down menu.
Takes a few days to break in, but once broken in I never take it off, except to shower. Comfortable and functional.
