I carry as little as possible cat hunting. A firestarter, wool gloves, and a hat. Also, an extra medium-weight shirt and an extra battery for my dog tracking equipment. That's all I carry in my pack.
I have a Stone Glacier 15-degree bag and a Klymit pad with a Nemo pillow when I am hunting out of a tent.
Lion hunting clothes have to be able to keep you warm when it gets cold and you're not moving. You also have to be able to walk all day in deep snow and steep country and not overheat.
I keep wool gloves and a wool hat in my pack at all times along with a dry wool next to skin shirt
I carry the lightest possible rifle for lion hunting that can shoot 200 yards in case a wolf is spotted
