And who doesn't need some of these?

Anti-Pervert Panties Block IR

In Japan, riding the train in a skirt is still an invitation to have your ass grabbed or photographed by some random perv. These days, there's a more advanced threat: cameraphones with IR night vision can be tweaked to see through clothes. Cramer Japan made these nylon and polyurethane panties that block IR, hampering the photographs. The name of the undies? ShotGuard Inner Shorts. The company is planning bras made from the same material.
