The Zoombang™ Football Compression Girdle utilizes Zoombang polymer, strategically placed in the hip, thigh and tailbone regions for superior protection. This is based on a unique energy dissipating material called Zoombang Polymer. Zoombang Polymer is a new visco-elastic polymer that is a soft, pliable liquid at rest. However, when a sudden shear force, such as shock, is applied the material immediately changes physical characteristics and stiffens to dissipate the energy. Once the force has passed, the material transforms into its original conformal cushioning state.
