DIFFERENT TYPES OF GRIPS
There are three different types of grips/overgrips, you'll find more details on them below. Each one has different properties that will answer to your expectations and needs.
Grips improves the hold between your fingers and the racket handle. It helps you get a firm grip on the racket in your hand and also absorbs vibrations.
Overgrips increase the size of your handle and ensures you have the best possible hold on the racket. Overgrips have the same qualities as grips, however they are much thinner.
Towelling Grips have a rather different function to grips or overgrips as they are used to absorb any sweat coming from your hands. Their main quality is absorption, which is why they are made of cotton.
