Fancy a drink now, sir?

Here’s a novel idea – a water bottle that actually nags you on the exact amount of water you need to drink, not one drop more or less. The HydraCoach Intelligent Water Bottle comes with an integrated hydration calculator that measures the amount of water you’re supposed to drink once it computes your weight, duration and intensity of the exercise, altitude, and temperature. You can now be sure that you’re getting just the right amount of water throughout the day. Those who drink more than they should won’t be too pleased with the 22-ounce bottle though. The HydraCoach is available for purchase at $30 a bottle.
