Love these shorts. Felt supported during heavy menstrual flow. And Material is great for when I get HS flares down there.

These are the ONLY underwear I wear. There are so many different styles and levels of leakproof that I have a pair to fit any activity/occasion...even if it's just for daily wear. These undies are a sweet lilac color and are so buttery soft, with no panty lines! Love love love!

How to wash
Machine Washable: Wash with like colors, cold setting with mild detergent, do not bleach, iron, or dry clean.
Always refer to our Fabric & Care section for best drying practices.
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.
