Eric Barnes had a lifelong habit of drinking water out of old Gatorade bottles. His wife, Stacey, convinced him to try bottled water, but Eric wasn't satisfied. With sales of bottled water skyrocketing, and the majority of empty bottles ending up in toxic landfills, he wanted a stylish and sustainable alternative. Together with his friend Paul Shustak, Eric founded KOR to make an eco-conscious water bottle that people would actually want to use. The duo teamed up with RKS Design, a southern California firm, to create the KOR ONE Hydration Vessel. It's since made serious waves with its sleek cylindrical shape.
