This pack was MUCH better than I anticipated. It's about exactly the size I figured, but the level of detail is amazing. The LEAST-impressive pocket is the vertical slot on the front. See the long piece of webbing with the snap in the seller product photos? That keeps the zipper up so your stuff can't fall out. There's also molle-style loops across the front. This is a thin pocket, though, with no subdivisions inside. Every other pocket on this bag has the zipper running about 3/4 of the way around the pocket, so it opens almost completely flat. This is phenomenal since it makes the subdivisions in those pockets easier to load, easier to browse/use, and takes the bag from a mere pouch of stuff to a kind of work center. There's a simple side handle in addition to a hanging loop AND a padded handle on top of the bag when it's not slung. As you wear it the water bottle carrier is on your left, with side-panel molle, a D-ring, and a loop you can cinch down on your right. The main shoulder strap has three separate areas with two rows each of molle (no subdivisions of the horizontal span, though), plus a 2" tall loop of webbing and a metal clip. The back also has a giant Y-shaped strap that can put tension on the pack to keep it from sagging backwards as you wear it. Both the main shoulder strap AND the stabilizing strap have clips, so you can take it off in whatever manner you tend to prefer. The back itself has decent structure and support, plus a decent amount of breathable mesh and padding. Oh, and in case that's not enough, there's a semi-hidden zippered pocket that is the size of the entire back which you could use to either store more stuff or add as much internal support/padding as you want.Pics are included on this review, but to summarize:- Top pocket has a wide pocket (~3x7") and three elastic loops (2"h x 2.5"w)- Large bottom pocket has key clip and a single big pocket (~4x8) inside the "door"- Main pocket has two slip pockets on the back wall (side opening, top is big enough for an iPad mini) and the door has a side-opening slip pocket the full height/width of the door, plus a pair of zippered mesh pockets and a webbing clip that can help keep things in the slip pocket from falling out loose.Having taken the pack on a few excursions now I can say that it is as stable as a rock, even when carrying a bunch of water bottles. It doesn't swing or sway and even loaded up it stays close enough to your back that you don't tend to hit nearby stuff when you turn around. It doesn't have the storage of, say, a full-size backpack, but if you plan out your storage carefully using all of the pockets available you shouldn't be lacking much. It won't hold a bunch of textbooks, but it should hold everything you need for a day trip, or a hike, or for work trips. And to top it off, the bag is surprisingly cheap for all of the features it offers. I'll wear this one out someday and happily buy another.
