I wouldn't recognise it as any kind of designer bag.
I'd wonder why you weren't using a proper computer bag.
It looks impractical, no zip or internal dividers so your chargers/papers etc will be rolling about with packed lunch/water bottle /whatever else you are filling that giant bag with and will be on show to everyone walking past your desk.
Sorry style over substance.
Get a leather Knomo bag if you have all the laptop peripherals to tote around. Do you work in fashion or somewhere you have to show off designer labels?
I killed a laptop due to just carrying it around carelessly until the internals got tired of being bumped.
