The inserts are made by Rocky Flats Gear based in Las Vegas, Nevada, USA and form the shape of a fig leaf (for men) or clasped hands (for women). They are also suitable for use in the chest area.

The powders block or diminish Alpha and Beta radiation, T-Wave/Tera hertz radiation from remote strip cameras and X-ray/gamma radiation from back scatter x-ray machines.

The inserts are thin and conform to the body's contours, making it difficult to hide anything beneath them. They do not set off metal detectors.

The men's design has the fig leaf, while the one for women comes in the shape of clasped hands.
