Our Collection

The day one® collection was developed by Arda Saatçi throughout the entire Cyborg Season to meet the highest demands of an elite athlete. Every kilometer Arda ran on his 3,000 km ultramarathon journey contributed directly to the design and optimization of our performance pieces. From the selection of materials to the perfect fit, we’ve worked tirelessly to create products that not only withstand extreme conditions but also empower athletes to perform at their best. Each piece offers the ideal combination of functionality, comfort, and style, helping you reach your full potential, no matter the challenge. Discover the collection that takes performance to the next level, born from the Cyborg Season.
