Built-in patented protection that feels like nothing at all
How Leakproof keeps you dry, fresh, and in control:
Wicks away moisture from your skin and fights odor.
Quickly soaks up the liquid that’s moved down from the top layer.
Seals in liquid discreetly, so leaks can’t reach your clothes or sheets.
Our patented tech locks in leaks at every edge.

How to wash
Knix underwear is 100% reusable and machine washable, just like your regular undies.
Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.
Machine wash on a cold, gentle cycle with mild detergent.
For their longest life, air drying is best. Hang or lay flat to dry.
Fabric softeners, bleach, ironing, or heat from the dryer.
