"I have a similar bag from Victorinox that I now believe is in the Mobilizer series - evidently a step up in lines. It was just not quite large enough after I put my usual carry-on items in it, it was always a stretch to get the last item in. Granted I could get all the items in, but there was no room to shuffle things around easily on the plane to find what I was looking for. This bag is just the right size. I fly over 100K per year and this will go with me until it falls apart. The quality is not so good as the similar bag, material is thinner, it is less framed, and the BIG NEGATIVE - THE SHOULDER STRAP is thin and barely padded. Since I had the other bag, I transferred that much nicer strap to this one - otherwise, be prepared to buy a different shoulder strap. The thin strap twists easily, you find yourself unwinding it all the time, and the shoulder pad digs into you. A PASSPORT slot as found in the 'other' bag to which I referred would be a nice and simple addition as well."
"I love this bag. It is very compact and has many pockets to organize items. The main compartment has ample storage. My quart liquid bag fits easily in one of the side pockets. There is plenty of room for carry on essentials, exercise outfit, rolled dress, rolled slacks & top, light sweater, extra pair of flats, camera and electronic adapters, scuba mask-snorkel-boots-dive watch. I pack it tight and the bag doesn't show any problem with seams or zippers. If I'm traveling for 2-3 days, that's the only bag that I take. For a longer trip, the back open panel of this bag fits nicely overly my 20" roller bag handle. This bag does not have wheels, so when packed it weighs about 18 pounds. The padded shoulder strap is comfortable."
"The bag is just the right dimensions for holding a laptop and computer gear plus other small items. It can be used as a second bag which slides over the handle of a roller board or can be used as business brief case.
