HydraPak Flux 1,5L opvouwbare waterfles grijs

Meet the HydraPak Flux 1.5L collapsible water bottle, your ultimate space-saving hydration companion. Its flexible TPU walls roll up to a fraction of full size when empty, freeing precious pack space on any adventure. The 42mm threaded neck pairs directly with popular filters like the Katadyn BeFree, turning it into a lightweight backcountry filtration system. When full, the bottle stands upright for easy filling and drinking; when empty, it collapses and stows away effortlessly.
