Wimbledon White overgrips 3-pack
3-pack · £11.99

Overgrips

Soft, tacky synthetic overgrips for a comfortable court feel. Three to a pack, in a clear zip pouch. Pair them with any dampener, or pick a ready-made gift set.

Colour: Wimbledon White

Cut the ping. Keep the personality.

A dampener is a small silicone button that sits on your strings. It soaks up the buzz and the high-pitched “ping” after each shot, so every hit feels and sounds cleaner. Ours just look a lot better doing it.

Fit it in 10 seconds

  1. Go to the bottom of the stringsThe end nearest the handle, below the last string that runs side to side.
  2. Pick two strings that run up and downThe middle two look neatest, but any pair along the bottom works.
  3. Press it onPush it between them until both strings sit in its grooves. That spot is allowed in matches too.
Behind the scenes

From our desk to your kit bag

Court Gems started on court. We wanted a dampener that matched our racket and strings, said a bit about us, and that nobody else had. We couldn't find one, so we designed our own.

We still pack every order ourselves: each pair goes on a lilac card, into a holo pouch and out in a Court Gems mailer.

Good questions

The things people ask us most at the club.

What does a dampener actually do?

It softens the string vibration you feel and quietens the "ping" sound off the racket. That's it. It won't add power or spin, but it does make every hit feel and sound a little cleaner.

Will it fit my racket?

Yes. Our dampeners grip between two main strings, so they fit standard strung tennis rackets, adult or junior.

Can I use one in a match?

Yes. The rules allow a dampener as long as it sits outside the pattern of crossed strings, which is why it goes below the last cross string.

What's in a gift set?

Three overgrips in one colour and a matching pair of dampeners. It costs less than buying the grips and dampeners separately.
