Platypus Platy Water Tank 4.0L Pocket but like every roll-top fabricHaving a few extra gallons of water around just makes things easier. Unfortunately, having a giant, empty container around doesnt. Therein lies the beauty of our Water Tanks. Collapsible by nature, they pack flat for efficient packing and our Big Zip opening makes filling and cleaning a breeze.
