This is an excellent bag for taking to the office, as a carry on personal item aboard an airliner, or as an overnight travel bag. The design is very well conceived and executed, with pockets for all of your needs, a nice padded laptop sleeve, and top quality materials and construction throughout. It feels a bit lighter than its main competitor look-alike, and a bit more compact in width, without sacrificing carrying capacity. This bag holds a lot, but it carries comfortably and without being bulky. The side pockets will hold a water bottle or umbrella securely. I take this bag on the subway, the bus, and to work every day, and it looks like new after over a year of use. This is one of the few real values in a multifunctional briefcase today.
