Bought this new a couple years ago, used it once then put it away and its been in storage since. Practically new - no stains, no smells, everything works as it should. Off the top of my head, I think is is around 2400cu. Has internal frame for heavy hauling if needed, side spotting scope pocket, bow/rifle holder, and built in rain fly. This pack cost $250 new - I will sell it for $175 shipped to your door.
