Each Zone pad contains a strategically placed insert filled with cells containing a material called Zoombang. This viscoelastic polymer is a semisolid at rest, unchanged by temperature or age. This means it conforms to a degree for comfort. The real test of any saddle pad, however, comes upon impact. This is when Zoombang's molecular structure instantly stiffens, dissipating shock over a wider surface area and reducing the impact of the blow. In milliseconds, after the shock has subsided, Zoombang returns to its original state. When you need the ultimate protection under your saddle, pick up a Zone pad and put science to the test. With durable orthopedic grade felt bottom it absorbs moisture, remains soft and pliable, and provides excellent shock absorption. 7/8 total pad thickness
