About Knix
Knix is a Canadian intimate apparel brand founded in 2013. It makes underwear, including leakproof styles, designed for comfort and for everyday bodily experiences such as periods, leaks and life after childbirth.
Why it’s a challenger
Intimate apparel has long sold airbrushed ideals and talked around bodily functions. Knix names leaks, periods, incontinence and postpartum bodies outright in its copy and shows stretch marks and C-section scars in unretouched imagery, treating underwear as a functional answer to real needs. By April 2024 it had passed three million customers.
This brand is in the Rival 50 2026 list. The report’s deep dives cover 14 of the top 20.
Reviewers’ view
Reviewers credited Knix for openly tackling taboo topics big brands avoid, like periods and postpartum bodies, with real imagery. They pointed to its Pints & Periods event bringing dads into the conversation and its Life After Birth postpartum photography project.
