The London Midi has an inner zip plus clasp. Inner pockets are great for keeping stuff in too.
Classic bags don't go out of fashion. I've previously bought cheap bags before and they lose shape and don't stand the test of time.
I dithered about spending so much on bags, but after seeing friends with bags that have lasted decades, I decided to invest in quality bags.
I have 3 now and wishing for the midi in evergreen pebble to come back on stock.
