I am going to Yellowstone park on a tour. I need suggestions for a camera bag, probably a backpack. I need it to hold my DSLR, Sigma 2.8 17-50 & canon 100-400 lens, batteries, memory cards & charger. Possible a jacket. Under seat size would be my first choice, but overhead will do. Any suggestions would be appreciated.
I recently got a Lowepro Flipside 300. I think it would hold all you want, except probably the jacket. A nice feature of this pack is that the zipper is not exposed to the elements and strangers. It is up against your back. To get into it, you swing it around front, and a belt holds it in place while you open it.
