Product Description

Total peace of mind with a supportive, no-show fit. Whether you are managing an ultra-heavy period, postpartum recovery, or intense bladder leaks, the SuperPlus No-Show High Rise is engineered to keep you dry. The moisture-wicking and anti-odor fabric pulls liquid away from the body instantly, offering a sustainable, eco-friendly alternative to bulky pads. Designed for a "barely there" feel, these high-rise panties stay in place without digging or rolling, providing all-day comfort for even the most active schedules.

Comfort-First Fit

High-rise silhouette sits at your natural waist and offers medium coverage for the bum, combining comfort with a flattering fit.

Ultimate Leakproof Protection

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

Day & Night Comfort

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

Machine Washable

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

    Lifesavers

    These undergarments have surpassed my expectations. I have tried a few other brands and these surpassed all the flaws of the other brands with flying colors.

    Really happy with new SuperPlus design!

    I bought the SuperPlus Leakproof No-Show High Rise underwear in a smaller size than my last order and am really liking this smaller fit!

    I've noticed that there was a bit of an odour with the other Knix Leakproof styles with less protection that I purchased within the last couple of years and the new SuperPlus style does not have the same odour! I am grateful that the materials used have possibly changed? and these new pairs I've purchased the last 2 orders are odour free.
