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.

    Anxiety Reducing

    I bought these for traveling but will use them when I get home too. As a larger woman in perimenopause with unpredictable cycles these have taken away SO much anxiety. They don’t roll or bunch. The material isn’t so slippery that your clothes fit differently either.

    These were recommended to me & I will recommend to others also.

    Extra security

    The undies do a good job of keeping your pants dry should you have urgency and a leak. They provide an extra layer of security that is a comfort.

    You win!!

    I have ordered and actually tried nearly every single incontinence panty out there in the universe, including your competitors Everdries and Evella...as well as many of the less expensive Asian brands on the market, just to be completely fair. HANDS DOWN, Knix has the edge on leakproof underwear!!! I have recently developed some major bladder issue since a terminal cancer diagnosis...and I'm not talking a dribble or a "leak" either! A "leak?" There is no stopping the stream to "make it" to a toilet...so when it's happening, it's happening - full bladder! I can vouch that Knix SuperPlus Leakproof High Rise underwear are the real deal ladies! Despite pads and/or other fabric incontinence underwear, I was FLOODING thru everything I was wearing. Finally, a product that actually does what it claims it will! I have no idea how much fluid 7-11 tampons equals or holds, but these seem to catch a moderate to heavy amount of urine and the absorption rate is equivalent to its "drip-time." I am SOOO satisfied with these undergarments and had nearly given up, but now I can "make it to my grave" with one less humiliating or embarrassing problem to deal with, and keep my feminity and dignity intact without wearing a "diaper" to the end! This is my second bulk order to Knix, AND includes a second order of the washable pads too, as they also work very well - although they also need to come in a lighter color too, BTW. Every single item in my last order was really liked, and earned 10☆ in…
