How to Choose Tennis Grips
Overgrip or Replacement Grip?
Overgrips are thin wraps (about .5mm thick) that go on top of your existing grip.
Overgrips are ideal if you want to change the grip's surface, or if your existing grip has lost its tacky feel. Replacement grips do just what they say - replace the entire grip, all the way down to the bare handle.
Replacement grips have the same surface and feel options as overgrips, but they also allow you to change from a firm grip to a cushioned one or vice versa.
