does this hook on to any portable camping water bag?
JOSEPH F R This fits onto the ening on MSR's water bags. I think they have the same size threads as Nalgene bottles.
KYLE G I think only the MSR bags. My guess is that they all have their own size to thread onto.
MICHAEL S It's a standard nalgene Bottle size, and fits on the msr dromedary bags. Hope that helps.
JEFFREY J It will hook up to any MSR waterbag. I don't know about other brands or water jugs
MICHAEL S I don't believe it does. It connects exclusively to MSR's Dromedary bag.
