SuperPlus Leakproof® No-Show Bikini

The most absorbent invisible period panty ever made. The Knix SuperPlus Leakproof No-Show Bikini is engineered for your heaviest days, absorbing an incredible 7 to 11 super tampons’ worth of flow. Despite its massive capacity, the seamless, raw-cut edges ensure it stays completely invisible under your tightest leggings or skirts. Featuring an extra-long gusset for 360-degree security, it’s the best high-absorbency no-show underwear for those who need maximum protection without the bulk.

Classic mid-rise bikini silhouette with medium coverage for hips and bum.

Our longest, most absorbent liner ever—front-to-back coverage without the bulk.

Buttery-soft stretch fabric moves with you, while bonded seams keep leaks contained and create a smooth, seamless look under clothing.

Wash just like your regular underwear—easy, everyday care.
