Good quality zippers and construction, but definitely geared towards the right-handed user. The key hook is on the right side, as is the water bottle pocket, which is quite snug, by the way.  I use a cane in the right hand, so I need keys and other items more accessible from the left-hand side. I've added a slip to the small tab on the left-side near the handle (tabs are on both sides). Nice number of pockets, though the front flap is a bit cumbersome to do one-handed (which, aren't most of us grabbing for things with one hand while the other is occupied)? I do wish it were a bit more squat in height, but it is true to the description on the website.  I do like that it's RFID, and it has a long enough strap to fit cross-body style for a variety of body sizes, which many do not.
