Measure "hand width": With the hand open, place a measuring tape (or thread) around the knuckles of the hand, excluding the thumbs. Now clench your hands to your fist and take the measurement.
Measure "hand length": From the fingertip (longest finger) to the bottom of the palm (above the wrist).
Specified sizes are indicative. Each hand is individual, so deviations are common. The table is only to be seen as a guideline. Some Giro glove models (e.g. "Remedy") are a little tighter, if necessary choose one size larger. |
