The AX band has been designed ergonomically using anthropometric data; this means it should fit 95% of wrists of all adults. We have also taken great care in designing the band to be worn on either the left or right hand with a gender un-specific approach.

Wrist sizing for the band is: 5.5 - 8.5" / 140 - 217mm.
