Somehow it doesn’t feel like you’re wearing a maxi pad, and it’s pure comfort all day. Since finding out menstrual disks and cups don’t work for me anymore with a prolapse post childbirth, I was pretty upset to have to use pads. But this option has saved my life haha! Soooo much better than any other external period product on the market!

I have a heavy flow but I picked up the mediums just to see how they did. Honestly I'm amazed. Not only did they hold up but they are comfy to wear. The flow didn't settle on the top and you could barely tell there was anything there. Zero leaks at night. This was by far the best purchase I have ever made

Your leakproof questions, answered.
Our Leakproof technology features a built-in absorbent liner. Depending on the style you choose, the absorbency can range from about 1-17 tsp of liquid. The result? Confident protection from sweat, discharge, periods, and light bladder leaks.
A gusset is essentially a liner. It’s where you’ll find our leakproof technology. It’s built into the crotch section of the underwear.
Coverage at Knix comes in all shapes and sizes. If we’re talking about silhouettes,, we go all the way from thongs to boxers.
We also offer high rise styles, like the Leakproof UltraThin No-Show High Rise, that sits just above the natural waist and gives full coverage through the stomach, hip & bum.
For extra liner coverage, look for undies that have an “extra-long liner” (usually 10”-14”), like in our Dream Short. And our Ultra Zones+ also have full bum coverage, too.
Have a suggested style or coverage? Just let us know. We love the feedback!
Leakproof covers you for all of life’s leaks, like periods (including your heaviest flows), sweat, light bladder leaks, postpartum, and discharge.
