Abstract
Abstract The protective padding (10), characterized by liquid-water impermeability and water vapor-permeability is provided. The padding comprises a middle layer of stretchable padding (12) and top and bottom layers of breathable films (14). If the inner layer is secured under tension a conformable product results which is useful in some applications. The padding may be used, for example, as the underpadding for orthopedic immobilizing devices and as insulation capable of withstanding water immersion.
