The FRIO Insulin Cooling Case is a reusable evaporative cooler whose cooling properties do not come from an icepack - or anything that needs refrigeration. Its cooling properties come from the evaporation of water. When activated, it keeps its low temperature for a minimum of two days, even in temperatures of 100 degrees Fahrenheit.
With the FRIO, the person dependent on medication that must remain cool is not dependent on ice packs in any way or at any time.
