day one® designs premium performance sportswear and accessories for people who train to get better.

Founded in Berlin by Alvaro Gellings and Arda Saatçi. Arda is a Red Bull ultramarathoner whose latest Cyborg Season project was a 600 km run from Death Valley to Santa Monica Pier. That mentality goes into every product: uncompromisingly functional, built for real performance.

Our principle: Every day is day one®. You are not bound by what you were yesterday — every morning, you get to decide who you are.

Today we're one of the fastest-growing D2C performance brands in DACH: profitable, intentionally small, built for the long distance.

We're building the team — for people who work the way our customers train.
