Hydrapak Flux Bottle (2026)

The HydraPak Flux is an ultra-light reusable bottle that combines the best of both worlds: shaped like a hard bottle, it compresses like a soft flask and cuts weight by 50%.The twist-drink nozzle with dust cover delivers grab-and-go hydration, while the flexible bail handle keeps the bottle secure in your hand or attached to your pack. Standing upright when full, the Flux packs down to pocket size when empty for easy storage.

Covered by HydraPak’s Beyond Lifetime Guarantee.
