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.

Disappointing quality
I've had these thigh savers for a year, and likely worn them about 30 times. The crotch is coming apart at the seams. For this price point I would've expected better quality. The 6 inch ones are perfect for us tall (5'10") girls. I found the shorties were gobbled by my thighs. I wish they had lasted longer as they are really comfortable.

Great for wedding dresses!
We tried on 5 or 6 brands and Knix was the only one that was truly seamless for my daughter’s wedding dress. Truly impressed! Thank you!
