Our Leakproof Period Underwear features triple layer technology that ensures you stay fresh, dry, and protected. The top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the leak resistant outer layer keeps any liquid from spotting your clothes.

Depending on the size and style of underwear, the leakproof gusset ranges from around 7.5” to 9” long. Our Super Leakproof Underwear features a 25% bigger gusset, with more of the coverage in the front of the underwear. For overnight leakproof protection, our Super Leakproof Dream Short gusset ranges from 10” to 14” long.
