For many years I had a Jansport computer backup that served me well, so, when it was ruined by contact with a noxious liquid, I was looking for something that was similar.  I selected this bag because it seemed very similar in size and features; it is, but, in many ways, it is better than my old Jansport bag.  I received it earlier this week and used it for the first time today.  I really like this bag.  It is made of a very high quality nylon.  The shoulder straps and back padding are comfortable.  There are two outside side pockets that can easily accomodate a 24 oz water bottle, a commuter cup or a small umbrella.  There is a nicely padded handle on top, and a smaller one between the shoulder straps, probably intended for hanging the bag on a hook.  On the front there are two zippered pockets.  The lower pocket is small and probably intended for a pair of sunglasses.  The upper pocket is large with a lightly padded sleeve for a tablet (my iPad fit comfortably) as well as several pockets, pen holders, a hook for keys and a reasonable amount of room for miscellaneous stuff. There is another, open pocket on the outside of this one with a velcro closure; I haven't figured out yet how I will use this pocket.  The center compartment is fairly large and, for instance can accommodate a full size DSLR camera and lenses, as well as other miscellaneous stuff;  There are several pockets, some zippered, some not.  The rear compartment is a nicely padded laptop pocket that easily held my 15 inch MacBook Pro.

Walking around today I had the MacBook Pro, the iPad, a camera, miscellaneous cables, a commuter cup and an small umbrella.  Everything fit comfortably in the bag with plenty of room left over.  It was very comfortable to carry on either one or both shoulders.
