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.

    Super leak proof

    These are super leak proof and are high absorbency. I bought the wrong style from my knee. I don’t need this heavy of leak proof protection, but they are leak proof.

    Super plus high rise

    I am trying something other than the cotton leak proof underwear and so far, so good. I wasn't sure I'd like the feel of the material but it doesn't bother me. I still prefer the cotton, though.
