• These underwear feature our signature buttery soft fabric.
• No show construction is designed to be invisible under clothes, including workout leggings.

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.

Turning 55 and desperately looking for comfortable underwear with no panty lines. I wanted something that washed well and would last. I purchased the light teen for a bit of protection against possible bladder leaks when exercising and long walks. These are perfect!

The product is a great quality but the absorbent pad is too short and doesn’t prevent even very light leaks. However the customer service is very good and they offered me an alternative product that fits more my needs
