| Had a similar dilemma when buying on line. I tried a few pairs on in a local shop just to be sure. But if you don’t have time…my hand measures widest point 105mm. Finger length, tape held between closed fingers1&2 80mm and 90mm between fingers 3&4 85mm and 60mm between thumb and hand 60mm.
I use gp tech xl and wouldn’t want um any smaller, hope that’s of some use. |
