For the second weekend in a row, I have failed to replace it. This is because I can't decide if I should follow the advice of one of my trusted colleagues and get a more "professional looking bag":
Or stick with the backpack solution (probably better for the back...):
I travel a lot! Mostly it is not to customer sites. Maybe once a month. However, when entering an important meeting with a suit, nice shoes, and styled hair, the backpack thing just doesn't work too well.
Hmmm, maybe I'll just have to get both...
