Hydro Flask was founded in 2009 by Travis Rosbach and Cindy Weber, due to their dissatisfaction with commercial water bottles, originally and formally known as Steel Technologies LLC. Originally based in Bend, Oregon they enjoyed early success at local farmers markets - especially among the outdoor recreation community there.
