Anyone make one before? I can't get myself to buy a hydration "system." Yes, I know new technologies are light and fairly cheap, but I'm not interested in becoming "one of those" type runners.
I'm thinking along the lines of an old can koozie, duct tape, a belt/strap, more duct tape, etc... You know, something fun.
I'm running 15-25 miles at a time with no access to mid-run locations.
