The Mission Darkness Faraday bag is like a faraday cage for your phone and other smaller electronic devices. This bag can protect your privacy from anyone attempting to track your location, and it also protects against an EMP (Electromagnetic Pulse), whether man-made or a solar flare event.
Protecting your privacy is more important than ever, with numerous mobile apps tracking your location and storing that information. You never know when you might get caught up in a law enforcement dragnet for a crime you had no part of, you were proverbially in the wrong place at the wrong time. Jorge Molina found out the hard way when he spent a week in jail for a crime he did not commit because his location data placed in in the general proximity of a crime. Along with other circumstantial evidence, he was jailed and ended up losing a week of his life, losing his job, and losing his car. https://www.nytimes.com/interactive/2019/04/13/us/google-location-tracking-police.html
