Utilizing the innovative Big Zip opening makes filling and cleaning a breeze with the Platypus Platy Water Tank. Having a few extra gallons of water around can make the world of difference in any situation. Unfortunately, having a giant empty container around doesn't. That's what makes these tanks so great is that they compact flat, they are light-weight and it even comes in a freestanding design so it can stand on it's own. Make your day camp easy and pick up a Platypus Platy Water Tank!
