Travis Rosbach explains how dissatisfaction with existing reusable bottles led him to create Hydro Flask, a double-wall vacuum-insulated stainless steel water bottle. He describes his path through earlier businesses in fencing and sign-making, the technical and logistical challenges of developing manufacturing in China, and the scrappy early days selling bottles at markets and into retailers. The episode follows the company's rapid growth, financing crises, the arrival of an outside investor, and Travis's eventual decision to leave Hydro Flask.
