I just got my US Issue Molle II frame pack ( large ruck and sleep system ). Im curious, how do you guys carry enough water with these for a few days? EXCLUDING hydration bladders.. I just dont like them! Im talking bulk water here, I know I could get 4 canteens or so..but finding a way of holding 2 regular 1 gallon milk jugs would be sweet! And yes, I am aware of how much water weighs :-)
