In a 2012 study performed at Stanford University, results overwhelmingly indicated that the CoreControl Cooling Glove is just as or more effective than performance-enhancing drugs. Furthermore, not only is this thermoregulatory device legal in all sports, it is also 100% non-invasive when compared with injected drugs. CoreControl is a hand-held device that is used to rapidly extract excess heat from an individual. Developed at Stanford University in Stanford, California over 20 years ago, this device has been and continues to be used by the US military, NFL, NBA, and NHL teams, first responders, and hazardous material teams.
