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.

    Comfy

    Got these for postpartum. As a plus sized girl girl I will say these are way comfier than what the hospital provides. I wouldn’t waste my money on disposable underwear/diapers… I used these with a pad until things had calmed down and I highly recommend. Definitely keep a couple extra pairs in the diaper bag too just in case!

    Amazing.

    I can say that Knix has changed my life. I am older and coughing or sneezing or anything can cause me to pee a little or a lot depending. Night time is complicated. Anyway, adult diapers are terrible. Then a person ends up with the garbage. 30 underwear are bulky. And nasty. Knix are so comfortable , I love the material. So smooth and non-binding and under my clothing, nobody can tell! Seriously I am so grateful!! Thank you!!!

    Je les adore!

    J’ai un lichen scléreux vraiment mal contrôlé (problème de peau) et ces sous-vêtements m’aident beaucoup en absorbant l’humidité. Ça fait des années que j’ai des problèmes et j’ai vu une amélioration dès les premiers jours.
