This invention provides a flexible and dynamic energy storage and transfer device for safe storage and transport of temperature sensitive products and for therapeutic uses. The portable device includes interactive chambers containing energy receptor materials with thermal holding capacity for cooling and heating purposes. Various chambers may be included to provide varying temperature zones. According to yet another aspect of the invention, a secondary layer is used to respond to environmental temperatures including ambient and exhaustive storage temperatures to extend the energy exchange period and sustain a thermal therapeutic dose toward targeted area.
