I bought this bag for a trip to Rome/Europe and loved it so much that I retired my old briefcase and am using this backpack for commuting too! Fellow travelers and co-workers commented on the bag, it's sleek and professional looking yet VERY flexible and comfortable. Some have mentioned the lack of inside pockets. I don't think this is a problem, I have a sleeve for my iPad and keep 2 large envelopes in the bag for paperwork. For other items I use two stuff sacks.

The security features of the bag are great, thankfully we never had to "test" them! But we felt secure knowing that the bag strap was looped through the chair while dining on busy streets in Rome. I love how the zippers clip in. Ultimately you still need to be aware of what's going on around you.
