Already have a plunger and just need more cork? Get some Injection Tubes to further customize your ZipFits.

Here's an illustration: What happens when you throw a cork on the floor? It bounces back. Cork is not only a natural, renewable material, but also incredibly responsive and has high ductility and toughness. What does that mean? It means that the energy you put into your turn is actually transferred from your leg to your ski.
