The golf grip can be a very complex thing to learn for some of us. This rubber golf grip can be added on top of the club you are using over the clubs original grip.
The training grip has contours made for your left and right hand fingers to sit in the right place. After using this for some time, one can remove this and try to hold the club in the similar way after some amount of muscle memory has been made. This grip does not take up any space and can be put into your golf bag or your range bag and can be used whenever you feel like the grip is going off.
