Product Description

Total security from morning to night. Upgrade your cycle with the Super Leakproof No-Show High Rise, engineered for those who prioritize extra coverage and comfort. The extended gusset provides 360-degree protection against leaks, making it an ideal choice for heavy days or postpartum recovery. Crafted from moisture-wicking, anti-odor fabric, it keeps you dry and fresh without the bulk of a pad.

Comfort-First Fit

Sits at the natural waistline and provides medium bum coverage.

Worry-Free Protection

Patented leakproof technology delivers a barely-there feel, while bonded edges prevent side leaks.

Heavy Absorbency

Absorbs 6 Super tampons worth of liquid—perfect for heavy flow days, overnight protection, and light bladder leaks.

No More Panty Lines

Made from our signature buttery-soft fabric and designed to be invisible under clothes, including leggings.

Easy to Wash

Machine washable just like regular underwear.

    They are the best leakproof I've tried

    I'm age 70 with occasional UTI. When it happens I need an underwear that will absorb urgencies. The fabric is smooth and stretchy and maintains its shape. Another product I used had fabric that crinkled. I now have 7 pair. There are the best
