Tony Stark may have it all when it comes to wealth and riches, but there's one thing that's truly priceless among all his possessions -- his trusty Iron Man water bottle.

Running Stark Industries, romancing Pepper Potts, and flying around with the Avengers in their never-ending quest to save the world really takes it out of you, so how do you keep up the stamina for all that? Water, water, and lots of water.

While it might not be as technologically advanced as his other toys, it certainly does its job. This officially licensed Iron Man Nalgene Tritan 32oz Water Bottle is marked with milliliters and ounces so that you know exactly how much fluid intake you're getting for easy measurement.

The handy bottle is also cleverly designed to have a wide mouth so that you won't have any trouble popping in those ice cubes for a cool, refreshing drink. I mean, it can't be too breezy cooped up in that iron armor all day, right?

Just remember to take a sip after every well-deserved victory in battle -- that's something Jarvis or Friday won't be able to do for you.
