This has bee a great product for me to use as a messenger bag for my school books. The strap is thick, so I don't feel like I'm being choked when I strap it over my chest. It's thick and durable fabric is comforting because it needs to be able to handle heavy books. Big roomy pockets for my wallet and pens, and the side pockets are good for a soda or water bottle. If you're looking for a purse this is a little bit too big (unless that's what you're looking for). It's definitely military grade, and I've even received compliments on it from a few ex marines I go to class with! I also plan on using it as an overnight bag when I travel. I recommend this!
