Reinventing Intimates for Real Life

At Knix, we believe women shouldn’t be confined to what’s conventional. We should be free to be comfortable and confident, and free to be ourselves. That’s why what we do feels so unlike anything you’ve worn before. To put it simply, we make intimates that you’ll love to live in.

Proudly designed in Toronto, Canada.
