The main reason to wear a golf glove is to improve ones grip. A golf glove provides a better textured surface from the glove to the club, and creates more friction from the hand to the glove, to help prevent the club from turning in a players hand. In warmer or more humid climates, a golf glove helps hold onto the club when conditions tend to be more slippery. This reduces the need to clutch the club harder, reducing tension in the hands and arms.
