Review on Collapsible Container Outdoors Backpack Freezable by Billy Braggs

They are very light and seem to hold their shape well. I have used them to store water in the wild as they fold well in addition to being light weight. Their opening accepts platypus gravity adapters, making them convenient for storing purified water. The spout on the 5 gallon jug is fine, but it would be great if it also came with a screw cap. I have yet to find a screw cap that screws properly into a 5 gallon jug.
