All of the standards for gloves, but it is basically impossible to find one that fits me. My hand is about the size of a Mac keyboard. As in I lay it put flat and stretched I have my thumb on the fn to the left, my little finger on the right arrow to the right, the base of my hand at the bottom of the touchpad, and my index finger on the f8 key. I think the last pair I successfully bought was XXXL...and was still a bit small.
