Project Scope

a running kit for Molly Seidel

Following our Design to Fade design collaboration with PUMA in 2020, we were asked to dye a running kit for Olympic athlete Molly Seidel. ⁠The kit is dyed by cultivating pigmented bacteria on the fabric, resulting in organic patterns that showcase the bacteria’s lifecycle. 100% natural, 100% unique!⁠

It was her first marathon start in a year and a half, after a challenging time with sports injuries and ongoing physical and mental struggles. So our kit had to wait until she recovered. But her return was absolute fire.

In our kit she ran her Personal Best at the 2023 Chicago Marathon in October. Her time of 2:23:07 earned her a top-10 finish – and renewed confidence. PUMA based the 2023 Running collection on Living Colour, but only Molly has got the OG kit.
