Most men carry more than they used to. A laptop, a notebook, something for the gym on the way home, a charger that never quite fits in a jacket pocket. The bag that holds all of this is doing a lot of quiet work in any outfit, and it is the piece most men think least carefully about. An A4 bag sits in an interesting position in the wardrobe. Too structured and it reads as corporate. Too casual and it undercuts everything else you have going on. The ones we have pulled together here get the balance right, working across the kind of day that starts at a desk and ends somewhere less formal. We have been looking at leather options that age properly, canvas that holds its shape, and handles versus straps depending on how you actually move through your day. A good bag does not announce itself. It just makes everything around it look more considered.
