I use a fuel belt. Like Oakleaf I prefer the "belt" type.
Her's sounds more adaptive than teh Fuel Belt brand, but works the same.
I just can't run w/ a bottle in my hand. So the "flasks" that fit in are nice nad small. (7 oz or 10 oz). I am small soI like the 7 oz. You can get one that holds 2 bottles (I have) or 4 bottles. Plus it has a pouch in the back.
I get used to the feeling of somethign around my waist. I freeze the flasks
(w/ beverage in) the night before.
