(Cargo Collective)

Safeguard your junk while asserting your rights in this fetching line of underwear featuring the 4th amendment - the one about unreasonable search and seizure - emblazoned in metallic ink. The maker claims the words are readable on TSA scanners. "Let them know they're spying at the privates of a private citizen," reads one of their slogans.

I have not personally tried this product but it's a clever concept.
