I am trying to buy my brother a birthday gift. He wants to shift from a briefcase to a backpack briefcase in order to have less strain on his back. He would carry his laptop and a pile of legal folders, as well as an iphone, ipad, cords, wallet, a book or magazine, etc. He makes a lot of presentations and wants it to look upscale and professional. He would also like a lot of pockets to separate out various things he needs. We (my family) are willing to spend up to $500, though would love to spend less if possible. Any suggestions? Thank you in advance for the help!!
