We all identify with the Messenger style. This bag is a finely crafted briefcase with attention to every detail. The exterior flap will keep all your items safe from the elements and from unwanted access while on a crowded commute. It has a front swoop pocket to stow cables and cell phones. The interior is divided with an impact proof computer pocket. You can convert from a shoulder bag to back pack in seconds. Comes in all leather or leather and canvas combinations. 17wx12hx3.5deep
