Since its founding in 2010, United By Blue has been committed to the idea that a successful outdoor brand can do serious conservation work, and to date, has removed 1.5 million pounds of trash from the world's waterways through its organized group cleanups. Its efforts have been boosted by collaborations with fellow businesses that put sustainability at the heart of their values, like Maker's Mark. As part of this year's #CocktailsForCleanups collaboration, United By Blue and Maker's Mark will be co-hosting four cleanups throughout 2019 in Chicago, San Francisco, Houston and Los Angeles.
