Where it makes sense
DromLite adds 4L of collapsible storage at a listed empty weight of 150g. It can hold the camp reserve while personal bottles stay reachable during a walk. A filled bag contains about 4kg of water before the container, so check both the carry from the source and the way it will be supported for pouring. Choose a rigid jug instead when stable table dispensing matters more than empty packing space. DromLite stores water; it does not treat it.
The tradeoff
Soft format needs careful placement and handling; no filtration or purification is included
