Who We are

While Athens, Greece is where you can discover our beginnings, our global community is where you’ll find our soul. Learn about our journey, our community, what sparks real conversations and why sportswear is at the core of everything we do.

Founded in 2015 by Nick Tzilakos in Athens, Greece, Sumezu is a sportswear-inspired, technical athletic apparel company for men, women and kids. What started as a clothing manufacturing studio from his mother by day and sportswear fashion design by night soon became a standalone online store in 2020.

What We Do


Our store’s vision was to create more than a place where people could get gear to sweat in. We wanted to create a community hub where people could learn and discuss the physical aspects of healthy living, mindfulness, and living a life of possibility. It was also essential for us to create real relationships with our guests and understand what they were passionate about how they liked to sweat and celebrate their goals. Today, we do this in our store in Athens, providing top quality sportswear and clothes worldwide.


Our first designs were made for athletes to wear during training. Through plenty of feedback from our customers, ambassadors, and elite athletes, we now design a wide range of collections for fitness, yoga, pilates, running, cycling, training, and most other sweaty pursuances for women and men. Not to mention, our designers are athletes and sweat-minded people, too.
