Our Story

Our Story

KT By Knix was founded in 2017 as the younger sibling to Knix, one of the first brands in the world to champion period underwear.

Led by our founder, Joanna Griffiths, KT was created to give Teens their own space in the world of periods. Whether it's their first cycle or their fifteenth, the goal is the same: help teens feel comfortable, capable and confident.

‎ Today, KT designs period period protection specifically for teens so they can go to school, sports, sleepovers, and everything in between without missing a beat.

A note from our
Founder

I started KT because I believe teens deserve period products made just for them. Ones that feel comfortable, supportive and confident boosting.

Periods are a normal part of life, but for many teens they still come with stress, uncertainty or stigma. KT exists to change that.

Every purchase helps us build better products and a better period experience for the next generation.

Thank you for joining that journey.
