This bag is excellent for every day usage.  It may be a bit large if you are small framed, or have only a small amount of gear/clothes/items to transport.  If you are carrying a larger amount of gear, perhaps a computer, change of clothes, shoes, lunch, books, etc, this bag is ideal.  Maxpedition sells lots of add on organizers as well, that will stick to the velcro inside the bag, so you can organize things like pens, flashlights, phones, and other smaller items.  There are even gun holsters to stick to the inside of it.

You can get into the bag while it is closed through a zippered slot at the top, which is a great feature, allowing you to safely store inside items you might need relatively quick access to, like documents, multitool, flashlight, papers, knives, guns, camera, etc.

Overall I rate this with 5 stars as an every day carry bag for those that need to pack a bunch of junk with them.  Looks more professional than a backpack, and is much easier to get into to boot!

Everything I've said about this bag also applies to the Maxpedition Gleneagle.  It is pretty much the same bag, just larger than this model.
