I truck my leather Brooks Brothers briefcase to and from the office and I know the MT guidance going back a decade+ is that backpacks (nice ones) are no-go. But often, I have a coffee in hand, sometimes carrying my lunch, plus the briefcase and open doors, climb stairs. A backpack would be much easier. I don't work at a Fortune 100 or anything. I am the highest IT professional for my organization. I never wear a suit to work (usually button-up and chinos/trousers) and occasionally wear a blazer. Has guidance changed in 2020? One thing I saw as a "sign" is Hartmann doesn't even sell briefcases anymore on their website. But they do sell some sweet backpacks! Check these out:
What do you use?
