"Stashitwear"

Brooklyn police officers were involved in the ultimate "debriefing" last month when a prisoner being questioned told them about the latest in criminal fashion: underwear with secret pockets.

A memo circulated to all members of the New York Police Department, and viewed by The Wall Street Journal, warns officers to be aware that "drug dealers are using underwear with secret pockets sold in stores from several different companies to hold drugs and small weapons."

Instead of the standard light pat-downs around suspects' waistbands, the knowledge that this secret underwear exists is going to cause police to have to undertake more thorough searches of some suspects...

Police research, he said, shows that secret pocketed underwear comes in a variety of styles—briefs, boxers, thongs—and is sold by dozens of companies...

Company owner Phillip Scott, 55, of Bonifay, Fla., said he has been selling pocketed underwear since 2006. He sells his underwear for $14 a pair, less if you buy wholesale. Its target market is not drug dealers, says Mr. Scott... "I always stashed my money when traveling so I don't lose it or get pick-pocketed," Mr. Scott said...

The pocket goes all the way down the front and up the back side. According to the website: "this basically makes your whole crotch area a secret place for your valuables."
