About the brand

Knix is redefining intimates by building products the industry overlooked. Founder Joanna Griffiths launched the brand after becoming frustrated with the lack of innovation in underwear, particularly for people dealing with leaks, and invented leakproof underwear to fill the gap. What started as a single-product idea has become a category-defining line spanning bras, leakproof underwear, swim, activewear, shapewear, maternity and nursing, and sleepwear.

The brand is built on customer-driven design, a commitment to inclusivity, and a willingness to talk openly about the things other intimates brands avoid: periods, postpartum bodies, leaks, and menopause. Knix also operates Kt, a sub-brand focused on leakproof underwear, swim, and activewear for teens. Between the flagship Toronto-based business and a growing network of retail stores, Knix has built a community around the idea that intimates can actually make you feel at home in your body.
