This underwear contains a tracking device that will surreptitiously monitor the wearer:
"Forget-me-not panties will help protect the women in your life!
These panties will monitor the location of your daughter, wife or girlfriend 24 hours a day, and can even monitor their heart rate and body temperature.
Based on pioneering research developed by the U.S. military at DARPA (Defense Advanced Research Projects Agency), we have brought this revolutionary technology, previously only available to the military, to you!
These "panties" can trace the exact location of your woman and send the information, via satellite, to your cell phone, PDA, and PC simultaneously! Use our patented mapping system, pantyMap®, to find the exact location of your loved one 24 hours a day.
The technology is embedded into a piece of fabric so seamlessly she will never know it’s there!"
