2 gloves if it's cold or wet. No glove otherwise. There really isn't any point in one glove. Either you need gloves for extra grip on both hands, or you don't.
Some on here quite openly tell about putting the glove on is part of their pre-shot routine ???????? Talk about reasons for slow play. (no, second thoughts - please don't)
And how do the custom fitting devotees deal with the number of tape layers required under the left and right hand parts of the grip? A glove must be the equivalent of at least 2 or 3 layers of tape.
