Meet The Sloth & The Duck

Built by runners. Printed to order.

Scott is The Sloth: the ultrarunner who keeps moving long after the pace stops looking reasonable. Laura is The Duck: calm on the surface, paddling like mad underneath. We started Sloth & Duck in 2023 to make gear for people like us, the ones who finish what they start whether anyone is watching or not.

Today the crew includes Rachel, our brand ambassador who runs our social and website, and Kenna, who helps shape the designs.
