Soak the plastic hoses in coffee for a week THEN run flexible stainless steel tap hoses thru them, the 'spring' in the hoses will help in straightening the hoses as you flex and extend yr arm allowing them to run up ur sleeve without them moving out (avoids looking like you have been doing only bicep curls with yr right arm LoL).. you bunch the ends of all three hoses (RoTJ ) and anchor with elastic to the top of your sleeve..Kills 2 birds one stone so to speak. Clear as MUD hey ..anyways my 2 cents ..
