I have a small backpack for my dSLR but with the recent purchase of a Tachihara I'm going to need another one.

Besides the camera, I'm going to need room for the usuals but not particularly large. It would not be for long, multi-day hikes either. Something comfortable.

I live in a small town with no real photography stores so I'm going to have to travel elsewhere to try them on. But for now I'd appreciate some recommendations at least narrowing down the kinds that I should look for.
