Our Absorbency Guide
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!
Many people refer to them as period underwear or period panties. But leakproof underwear covers you for all of life’s leaks, including periods (even your heaviest flows), sweat, light bladder leaks, postpartum, and discharge.

I 100% recommend it!! I have 2 other knix panties and they were amazing. This is the first time I've got the thong, and I will say it's so comfy. I mainly got it to wear to the gym with my shorts because I hate having to use panty liners all the time. It does not give me any camel toe, and it is literally perfect. My waist is 28inch and my hips are 40 inches. I got a size medium and it works great. I could've sized it down, but this is still very comfy.

This thong fits perfectly and is so comfortable. The leakproof lining is comfortable as well and unnoticeable. I found the full bottom underwear too big but this thong is perfect!

I don’t wear thongs often but wanted to try this brand for light leaks and it is very comfortable. Hardly know it’s a thong. I typically wear a Large in Knix but I ordered the XL in the thongs. Fits perfectly.
