Regripping every year is a good idea. If you play multiple times a week you may want to consider regripping more often. Clean your grips with soap and water after every round. Be sure to dry them as well. Don't keep you clubs in the car during the hot summer months.
Heat can break down the tape and grip compound leading to a shortened grip life.
We offer grips from Golf Pride, Positrac, Griptec, Royal, Winn and Golfsmith.
