Dunlop Hydramax Pro Replacement Grip The Dunlop Hydramax Pro Replacement Grip is a very comfortable replacement grip. The hydramax surface is designed to absorb sweat very efficiently. This optimal moisture-absorbing capacity not only gives you that little extra comfort, but also ensures that the racket does not spin or slide in your hand. The Dunlop Hydramax Pro Replacement Grip is made up of five separate layers which guarantees the maximum comfort. The Dunlop Hydramax Pro Replacement Grip is equipped with a premium PU non-slip layer at the top and is therefore the ideal grip for ambitious squash players who want to perform optimally on the court. All rackets from Dunlop's top line (the Precision and the Hyperfibre + models) are standard equipped with the Dunlop Hydramax Pro Replacement Grip.
