I have used this bag once. For a carry on, the size is perfect, and I love the color. The collapsing handle was a little sticky the first few times I used it, but seemed to "find its track" after my first run through an airport. The soft handle design was versatile as I could clip a smaller bag to it. The thing I liked the most about this bag is all the zippered and slip pockets. There are zip pockets in the front pocket. Once you open the main pocket, there is a removable toiletries panel, with three zippered pockets, one of which is lined in vinyl, so it is waterproof for any damp items, another is mesh for breathability. There is another flap that has zippered pockets that serves as a wall to keep items in the main compartment in place. Oh yes, and there is another panel in the back with two more zippered pockets, one vinyl lined and one mesh. There are two more external vinyl lined pockets on each side as well. The only complaint I have is that on my first trip, the stitching along one of the seams on the internal panel came out, and the zipper came off. I was able to get the zipper back on, and it is probably not a pocket I will use much, so I did not think it was worth the hassle of returning/warrantying the item. For the price of the bag, I'd think they'd do better quality assurance on each item.
