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.

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.

Knix designs and develops all products in Canada. However, the brand uses sustainable manufacturing facilities in China and South Korea.

Essity Hygiene and health company Essity acquires 80% of the Canadian company Knix Wear Inc. (“Knix”), a leading provider of leakproof apparel for periods and incontinence.

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.

Designing all of their garments in Canada, and producing them ethically in factories in both China & South Korea, this company is making our hearts happy not just with their products, but also with their devotion to keeping things on the up and up.

At Knix we do not intentionally use PFAS in the manufacturing of our leakproof products. However, PFAS are now so widely dispersed in the environment that even the water we drink has low levels of contamination that, unfortunately, cannot be avoided.
