sorry to revive this thread, but I just got my reload bag in the mail today. it's stellar -- couldn't ask for better. the thing is totally and utterly massive (courier model) relative to my skinny body, but even with some minimal wraparound, the thing stayed on my back fine while riding with no slide whatsoever. I was quite worried about that, but it seems fine -- at least in my winter gear. i can probably fit a couple of infants and some malt liquor in it, which is really all that matters, anyway.
