Has anyone tried this or heard anything about it? Do you think you could fit your camera gear in it and camera arm? Here is a link to it Gameplan Gear BowBat XL Hunting Pack - 648935, Hunting Backpacks at Sportsman's Guide
I own one and they are really nice. I don't carry camera gear around but if I didn't put my bow in it I'm sure I'd be able to. Fitz also has the bow bat. He would be a good person to ask.
