I still use a DeWalt Tough System XL box. It has a gasket and very strong latches so it might not be easy for a bear to smell food in it, and would give quite a tussle to any hungry b'ar. It is easily strong enough to sit or stand on (and I'm 270 lbs) and makes a great bench for lunch on the trail. Also, the tool rack along the back of the compartment is perfect for stashing eating utensils.
I cover the DeWalt logo with stickers to make it more overlandish.
"The area inside a black bear's nose, called the nasal mucosa, is 100 times greater than ours. This large nose results in an excellent sense of smell! Even bloodhounds, dogs so famous for their sense of smell that they're used to track missing people, don't smell as well a black bear. It is estimated that black bears' sense of smell is about seven times greater than a bloodhound's."A bears sense of smell is on par or better than a Bloodhound. A bear can smell whatever is inside a DeWalt box.
