Frequently asked questions
What is Undercurrent?
We create the first layers you put on every day. Our goal is simple: to make sustainable, unisex no-show socks and men's & women's underwear that actually stay put. We design our pieces to never slip, roll, or chafe, so you can feel comfortable and confident from morning to night.
Is Undercurrent the same as ESSOC?
Yes, we are! We started our journey as ESSOC. As we grew and listened to our community, we realized our true passion was creating seamless, everyday essentials. We evolved into Undercurrent to better share this focus on smooth, reliable comfort.
Who founded Undercurrent?
Undercurrent was founded by Stella Liu. Frustrated by socks that always slipped down and underwear that never quite fit right, Stella set out to design sustainable essentials that gently support you without ever getting in your way.
