After years in the trenches, I'm adjusting to working in a corporate setting.

Been using this nice lil bag I got for carrying vinyl to haul my laptop, umbrella, etc but after walking back and forth from the office to the commuter train, I'm realizing that a shoulder bag is weighing me down on one side and I might be better in the long run with a backpack that's made for work.

I wanna get something nice, but I don't wanna be the guy with the Gucci drip that's just expensive for no reason.

Any corporate warriors have an opinion or recommendation?
