I am looking for a nice messenger bag for my son. It has to be an executive type bag.....more like a briefcase. He is so afraid of carrying one out of fear that it will look effeminate, which his girlfriend insists will be the case. But, he has scoliosis, and the shoulder strap would lessen the strain on his spine. I am trying to talk him into carrying one, that is, if I can find the right one. Any ideas anyone? Thanks.
