Meet Our Best-Selling Brief
With a classic fit and full coverage that flatters all body types, the Leakproof Brief is a staple in the active woman’s undie drawer! The patented, multi-layer Leak-Loc™ system wicks moisture away from the body while providing moderate leak absorbency (that’s about six teaspoons of liquid, or about three tampons’ worth). The best part? These undies feel like her favorite pair, in a buttery-soft fabric with a thin but powerful liner.
