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.
