Reduce the annoying ping and harsh vibration from your tennis racket with these simple but effective silicone dampeners. The pack comes with 8 dampeners and a neat little gift case for storage (case size is about 3.15” x 1.57” x 1.97”). Each dampener is about 4.72 inches (12cm) long and made of flexible silicone that you weave or knot into your racket’s strings. They work by absorbing the shock and vibration when the ball hits the strings, which can make your arm feel more comfortable, potentially reducing elbow strain, and giving you a softer, more controlled feel. They also change the sound of impact to a more muted ‘thud.’ They’re known for staying put and not falling off during play. Easy to install and remove, these are a must-have accessory for many tennis players looking for a bit more comfort and a different feel from their racket.
