Unexplained Crewneck Sweatshirts

Description: In one of the longest-running science fiction series in network TV history, FBI special agents investigate unexplained, mind-bending cases known as "X-Files."

Description: Some signals are easier to receive than explain. Established in 1952—or so the paperwork claims—the Department of Unexplained Signals maintains a watchful ear on the frequencies nobody else seems particularly concerned about. Radio telescopes scan the night sky. Oscilloscopes flicker. Frequency logs accumulate. Somewhere beyond the static, something may be answering. 23.7 MHz. 42.1 MHz. 88.6 MHz. …and still no clear answers. Inspired by Cold War radio astronomy, mid-century scientific instrumentation, forgotten observatories and wonderfully optimistic 1950s science fiction, this distressed faux-agency insignia celebrates humanity’s persistent habit of listening for things we don’t understand.
