Flux™+ 1.5L soft water bottle

Flux™+ 1.5L is a soft bottle with a built-in filter for carrying and treating water in one system. It is made from lightweight TPU and uses a hollow fiber filter that removes common waterborne bacteria and protozoa, so it suits hiking and other use where safe water is not guaranteed. The filter is rated for about 1,500 litres with a flow rate of over 1 litre per minute. The bottle is shorter and more stable than many hard bottles, and it rolls up when empty to save space.

The filter lets you squeeze or roll the bottle to fill other containers, or drink directly on the move. A dust cover helps keep the nozzle cleaner and opens with one hand. One important limitation is freezing: the filter must not freeze, because this can damage the hollow fiber membrane.
