The HydraPak Flux 1L revolutionizes backcountry hydration by delivering the best of both worlds: the stability of a rigid bottle when full and the packability of a soft flask when empty. This innovative collapsible water bottle stands upright in your pack pocket during the day, then compresses down to pocket size once you've finished drinking, cutting weight by 50% compared to traditional hard bottles. The high-flow twist nozzle delivers smooth, splash-free hydration on demanding trails, while the 42mm threading accepts most water filters including Katadyn BeFree systems, making it perfect for backcountry adventures where reliable water sources are scarce. Whether you're pushing through a grueling day hike or settling into camp after miles on the trail, this lightweight hydration solution adapts to your needs without the bulk that weighs down your pack.
