Take the dehydrating experience out of long hours in an airplane with the Platypus hydration bottle. The Platypus holds one liter of water. After the traveler has sucked it dry, they merely roll up the empty container and slip it into their luggage or a pocket. Made of strong laminate that doesn’t lend a plastic flavor to the liquid inside, this bottle is reusable and will keep your travel-hound hydrated throughout their journey.
