What are the different types of available grips?

Base Grips and Overgrips are the two types of available grips

Base grips (or Replacement grips)These grips are placed directly on the handle of your racquet. The grips are thick and provide good comfort and should be wrapped on the bottom of all players racquets.

Over grips These grips are thinner grips that are cheaper than base grips. Over grips are wrapped over the top of base grips to provide better grip and can be used to add some extra thickness.Easily and quickly replaced, good for carrying in your bag during tournaments.
