I always had a problem keeping my hands dry during play. Summer time is the worst. After trying all different kinds of overgrips, the only thing I was reasonably happy with was a gauze....until my coach introduced me to What a Grip! For me, this is a game changer. The racket no longer slips in my hand and my shots, especially volleys, got much sharper. It's a good feeling that your racket is never pushed back against hard hitters. I thought putting it on a racket was a hussle, but it's not bad once you get used to it.
