Since I hunt, backpack, and ride, my initial response was "you gotta be kidding, I need ten different jackets and coats just to cover my various hunting activities" but I'll can that. You ask a tough question, not because it can't be answered, but because there isn't any information.
What kind of hunting and in what kind of weather?
What type of backpacking, in what terrain, in what weather? And I think here I would want to know for how long. Longer trips require lighter gear to accommodate necessary additional equipment and food.
What type of riding, in what terrain, and in what kind of weather?
