Palm Rejection Artist Glove for Graphics Tablets Pad Free Size Good for Right or Left Hand (2 Unit, Thick) by Unyield

Stops my Fujitsu T902 from registering errant touches. This is critical because the T902 has a digitizer firmware bug that causes stroke repeats based on touch events (even when touch is disabled). These gloves are thicker than the usual paper-thin ones. They'll even keep your hand warm while drawing, although that might be a negative if you don't have cold hands like me.
