Hydrapak Flux 1,5 L Mammoth Grey Water Bottle

Flexible bottles get an upgrade. The FluxTM is shaped like a hard bottle, compresses like a soft flask, and cuts weight by 60 percent. Topped with a spill-proof twist-cap for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. Finish your drink, and this bottle packs down to pocket size. With the FluxTM, innovation fuels performance.
