Our Leakproof Underwear features triple layer technology that ensures you stay fresh, dry, and protected. The anti-odor top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the leak resistant outer layer keeps any liquid from spotting your clothes.

Are Knix Period Underwear Worth It? Knix Period Underwear is a great find for those consumers that need and/or want a little bit more protection than traditional underwear provides. All of their underwear gives at least some moisture control and support.

Joanna Griffiths launched Knix with the goal of transforming an underwear market that had too much frill and not enough function. A trailblazer with the creation of Leakproof Underwear, she continues to focus on listening to what people want and bringing revolutionary solutions to life.

The patented technology built into Knix underwear locks in moisture helps get rid of odor and stops leaks. Moisture Wicking, Anti-Odor Cotton Layer: Cotton is a natural and breathable fabric. It wicks away moisture and is anti-odor so you can be confident all day long (no need to worry about period underwear smell.)

Absorbing up to 3 tsp of liquid or 2 tampons, Knix's medium absorbency undies are available in a variety of styles, like our classic Bikini and Boyshort. These are perfect to wear solo on medium flow days, or for your entire cycle if your flow is typically on the lighter side.

Yes! One of the biggest benefits of switching to Proof® is that leakproof undies are machine washable and reusable, so you can wear them again and again.

Super absorbent Knix leakproof underwear can hold up to 8 tsp of liquid (whether that's sweat, blood, or urine). Products like these can be a game-changer for those experiencing incontinence, allowing them to remain active and social while exploring treatment options.

Knix provides leakproof women's intimate apparel for periods and incontinence. Its product includes bras, underwear, activewear, loungewear, sleepwear, shapewear, maternity, and swimwear. It was formerly known as Knixwear. It was founded in 2012 and is based in Toronto, Canada.

Now another manufacturer of period underwear is in legal hot water because their products allegedly contain PFAS. The Canadian company Knix Wear is being sued by two California women because of marketing claims they say are misleading.

Instead, the gusset of Knix underwear features a fabric made of cotton, woven with carbon and spandex that contains microscopic holes in it that make it extra absorbent. “People tend to think that all period underwear is made the same way, but it's not,” she says.

You don't have to but you can. Our pads are designed to be worn with regular underwear but on really heavy days we like to pair them with period undies for more convenient changing. When the pad is full, remove it and wear your Leakproof or Super Leakproof Underwear alone for the rest of the day.

The amount of urine you're leaking will be the biggest determining factor for the kind of incontinence underwear you need. For example, super absorbent Knix leakproof underwear can hold up to 8 tsp of liquid (whether that's sweat, blood or urine).
