Meet your heavy-flow hero. Designed with an extended internal liner and advanced 360 LeakSeal™ technology, this high-rise style absorbs the equivalent of up to 9 super tampons–while still feeling soft, breathable and (most importantly) invisible under clothes. The buttery-smooth fabric and full-coverage fit make it an everyday essential you can truly rely on.
Minimal and mighty, this mid-rise thong offers a seamless, second-skin feel that disappears under even the tightest leggings–while quietly absorbing up to 2.5 super tampons worth of liquid. It’s the perfect pick for moderate flow days, light leaks or sweaty workouts when you want protection sans the bulk.
