Our Leakproof Period Underwear features multi-layer technology that differs from style to style, but works to ensure you stay fresh, dry and protected. For example, in our Super Leakproof™ No-Show Bikini, the top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the outer layer keeps any liquid from spotting your clothes.

Comfy and confident!
I absolutely love all of Knox products. True to size, if you have any questions the fitting agents are right there to help you! My concerns were quickly and expediently solved when I had them, and now I rely solely on Knix as my undergarment provider. Their products give me the confidence I want as a menopausal female with fluctuating needs. A++!!

Like the fit
I’m really happy with the panties they fit and are very absorbent. I’m disappointed in the shipping. They charge way to much and they did not get delivered when promised.
