The blk. company mission is to be an ambassador of health and fitness, to be an icon of form and function, and to support a healthy lifestyle that is conscious of the modern individual. blk. athletes dare to push themselves further than they thought was possible. They hit harder, run faster, sweat more and do it all with style. Whether staying hydrated at the gym, nightclub or beach, blk. athletes require more from their water. They need water infused with the powerful vitamins and trace minerals that will help them achieve and maintain optimal performance.
