It's both an art project and a practical clothing line.
...Harvey's line of "Stealth Wear" clothing includes an "anti-drone hoodie" that uses metalized material designed to counter thermal imaging used by drones to spot people on the ground. He's also created a cellphone pouch made of a special "signal attenuating fabric." The pocket blocks your phone signal so that it can't be tracked or intercepted by devices like the covert "Stingray" tool used by law enforcement agencies like the FBI.
