We’re redefining intimates
We design game-changing intimates, swimwear, and activewear that empower people to feel comfortable in their own skin.
About our Founder & President, Joanna Griffiths
I founded Knix to radically transform the intimates industry. Frustrated by the lack of innovation in underwear—especially for people dealing with leaks—I invented leakproof underwear and pioneered a new product category. Guided by real customer feedback, a commitment to inclusivity, and a mission to break taboos, I built Knix into a brand that celebrates the freedom to live unapologetically free.
