• So thin, you’ll forget you’re wearing anything. Our original leakproof technology offers a barely-there feel while absorbing about 1 regular tampon or pantyliner worth of liquid.
• Patented bonded edges help prevent against side leaks.
• 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.
• Extra coverage through the hip and bum
• Mid-rise silhoutte
• Thin, built-in liner, 7.5-8.5” long
• Absorbs the same as about 1 regular tampon
• Quick dry gusset
• Soft, stretchy PerformaStretch® fabric
• Conforms to your body
The fabric is designed to feel snug at first but relax with wash and wear for a perfect fit.🇨🇦 Free standard shipping over $100.

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.

These underwear give me the confidence I need at this point in my life that I won’t leak through if my period shows up unexpectedly or if I can’t get to the bathroom to change my tampon. They’re also nice for those times when I sneeze and have a bit of bladder leakage!
