HydraPak Flux 750 ml in Mammoth Grey is a collapsible sport hydration bottle designed for outdoor activities and daily training. With a 750 ml capacity and a flexible, lightweight construction, this bottle reduces bulk when empty by rolling or folding flat for easy storage.

Advantages

Its wide mouth simplifies filling from taps or portable filters and makes cleaning straightforward without specialised tools.

The collapsible design reduces environmental footprint compared with single-use bottles by encouraging reuse.

Rinse after use with sugary or acidic drinks to prevent residue and occasional deep cleaning to maintain hygiene.
