This is a military looking bag and has lots of room for a lap top and tons of other stuff.  I use it to lug my goods back and forth to work everyday.  Nice outside pockets to drop your keys into or a bottled water.  The front zip pockets under the front flap hold other small objects you can get to easily.  It could be worn across the body but if you are smaller, then it probably won't work as well as just carrying it on the shoulder.  It has a nice wide strap which really removes the cutting into the shoulder and making the bag seem too heavy.  It's a great going to work bag.
