Fits Like a Second Skin
A proper fitting golf glove should fit like a second skin, tight across the palm and fingers, with no loose material.
Fingers Should be Snug
You should not have extra material at the top of your fingers, if you do, you may want to size down or try a Cadet glove in your size.
Room to Adjust Closure
The tab should only come about 75% of the way across the back of your hand (leaving 1/4” of Velcro uncovered) to allow for adjustment during play.
