HydraPak Flux Water Bottle
Best collapsible hydration solution for weight conscious backpackers and hikers.
This is the ultimate space-saver for hikers who hate carrying empty, bulky plastic. It collapses down to almost nothing once you’ve finished your water, though you’ll have to sacrifice the temperature retention you’d get from a traditional insulated steel bottle.
