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.

Exceptionally comfy
I love all of my Knix period underwear. I've been using the super leak proof and leak proof undies for about 4 cycles now and adding the dream shorts the next logical step. They are so comfortable, I could totally wear them during the day on my heaviest day. I would also love a pair of nonleakproof shorts like this for sleep for the rest of my cycle.

Best period undies
I love these so much! I have 3 pairs and they are very comfortable. They are perfect for nighttime, I use mine as a backup with my menstrual cup! Can’t recommend them enough
