• The carbon cotton gusset top layer wicks away moisture from your skin.
• These underwear feature our signature buttery soft fabric.
• No show construction is designed to be invisible under clothes, including workout leggings.
• Machine washable just like regular underwear.
Our original leakproof technology is perfect for everyday wear (think sweat, discharge and light leaks), backup protection during heavier days or on its own for lighter days.
• Mid-rise silhouette minimal bum coverage
• Thin, built-in liner, 7-8.5” long

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!

I have been a Knix girl for a few years now (I usually buy the essential no show thongs) - this is my first time buying the light leakproof styles, I ordered simply because I liked the colours & thought I'd give them a try! One thing I noticed is they're definitely more snug than the essential line, but I know that's because they design them that way for the leakproof aspect. I don't mind because I know they will loosen a little & form to my body with wear. I may be converted to the leakproof now, I appreciate that it will absorb excess moisture. Knix is my go to for all underwear, you literally can't feel them while you're wearing them. Also invisible under tight clothes which is a must.

I love that I can wear these underwear anytime of the month and feel confident that I’m dry and protected from leaks. I feel so much more confident and comfortable in my Knix underwear compared to other pairs I own. I come back to these every time!
