Canadian Women's Undergarment Brand Knix Expanding Further with Stores and Significant Growth [Founder Interview] Joanna Griffiths launched Knix with the goal of transforming an underwear market that had too much frill and not enough function.

Knix, the incredibly popular Canadian menstrual and incontinence underwear brand, is currently facing a class-action lawsuit in the U.S that alleges, despite marketing claims to the contrary, that Knix products contain per- and polyfluoroalkyl substances, a class of synthetic chemicals commonly known as PFAS.

Capable of absorbing up to 40 ml of any kind of liquid (period blood, sweat, bladder leaks, you name it), you'll be able to ditch disposables like pads, tampons, and incontinence products for good. Before you grab your measuring cup from the kitchen, 40 mL is the equivalent hold of 8 regular tampons.

In addition to making the Knix line leakproof and comfortable, Griffiths wanted to make them as ethical and sustainable as possible also. The Knix product line is all designed from their offices in Canada. However, they aren't manufactured there. They are manufactured overseas in China, Seoul, and Italy.
