Heavy-flow protection can feel secure, flattering and virtually invisible beneath your clothes.

Its smooth construction sits discreetly beneath clothing, while the fuller fit provides comfortable coverage through the waist, hips and back.

Designed for heavier-flow days and overnight wear, it offers reliable absorbency to help you feel dry, secure and confident for longer. The soft, flexible fit stays comfortable as you move, making it a practical choice for work, busy days, travel and sleep.

It can also be worn for light bladder leaks, discharge or whenever you need added reassurance.
