It's all in the name 'InStill'. A still water beverage that is instilled with delightful real fruit juice combinations, and not with a bunch of ingredients you can't pronounce. We put it in a big 19.2 ounce can to keep you well hydrated. You can even put it back in the fridge after opening and because it's still, it won't go flat. This one's not for the pro athletes, it's for the working warriors out there trying to stay hydrated on the job, at home or on the go.
