Star Grip® grips are made from a more expensive proprietary industrial grade EPDM elastomer. All our grips are made here in the U.S.A at our factory in Chandler, Arizona. Traditionally grips get hard and slick over time as a result of salt, moisture, U.V. and ozone exposure. The material in Star Grip® grips is backed by our guarantee that it won’t get hard or slick, nor will it crack, split or absorb moisture. We simply ask that you take the “Star Grip® Challenge”. Switch over to Star Grip® and see what a difference it makes to your golf game.
