With the addition of locks on your bags, one habit I have with less important pockets (clothes, etc) are two-way zip ties. Easy to apply/remove (although some brands are better than others on ease if removal – my personal favorite are from Sinorefor Products Inc) they allow for travels to ensure your straps or pull cords aren’t accidentally opened when you snag on a corner; or nefarious elements. They are also inexpensive and don’t take up much room, unlike locks which can get bulky.
