The Gorilla Grip MoJo Traction Pad uses the Diamond III groove pattern to allow maximum contact with the grip. The MoJo was designed for extreme surfing. The Diamond III pattern is specifically designed to increase traction when you push your foot back and to reduce resistance while moving your foot forward. High quality foam is used to make a tail pad that's lighter on your board and easier on your skin. Gorilla Grip Traction Pads have a unique "G-Cell" Foam (used in the Mojo Pad) which is the highest quality Traction Pad material on the market. Gorilla Grip also uses 3M adhesive backing for long lasting hold.
