"Refeuling on the Fly"

[TsPoet]

I love my Bento Box. I can tip my sport beans and pretzels in there and then just grab them as I need. The one I have also fits a couple of sports bar. Using this I have extra room in my jersey pockets for any other gear I might like to take on longer rides (camera, bolero or more food).

Vote #2 for the Bento Box. I put a small sandwitch bag liner in mine and fill it full of stuff to just dip out and use.
If you want a bigger and lower bag try this one

While it's been designed for a recumbent, I think it would work as long as the top tube is long enough.
