HydraCoach isn't the Drill Sargeant of some evil military organization. It's not the beast master of a mythical multi-headed serpent. No, its a polycarbonate nalgene-type bottle that calculates how much water you should be drinking, reminding you to sip throughout the day until you've met your quota. Shows your daily intake in terms of percent. No idea whether this has a cola function to pace my USRDA of Pepsi.
