In 2010, Sarah Kauss started S’well with an audacious goal — to rid the world of single-use plastic bottles. At a time when sustainable products weren’t stylish and stylish products weren’t sustainable, she created the world’s first reusable hydration accessory. At S’well, they hope to be a spark for change.
