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.

PATENTED LEAKPROOF TECHNOLOGY

Our longest, most absorbent liner—ever.

Our original Fresh Fix Technology® features a built-in absorbent liner that soaks up about 7–11 super tampons’ worth of liquid—so you stay fresh, comfortable, and in control.

Soft Top Layer

Gently wicks moisture away while keeping you feeling fresh and odor-free.

How to wash

Knix underwear is 100% reusable and machine washable, just like your regular undies. 

  • Rinse

    • Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.

  • Wash

    • Machine wash on a cold, gentle cycle with mild detergent.

  • Dry

    • For their longest life, air drying is best. Hang or lay flat to dry.

  • Avoid

    • Fabric softeners, bleach, ironing, or heat from the dryer.

      Terrific Find!

      I am so pleased with my new Knix underwear. They are soft and comfortable and work well for minor leaks. They also wash up nicely but do stretch a bit after wear and wash. I ordered both size medium and large only to find size medium is much better for me as I wear size 12-14 pants.

      Super Leakproof review

      I am glad that there is finally a full coverage option. I am an active person and have found that I needed more coverage while playing golf and tennis. I had used the extra pads but that was bulky so now I can just use these and don't need the extra padding.
