My "mobile workstation" and "life storage container" are exactly this Jansport. 

I like its understated and elegant coconut brown color, which goes well with any outfit.
What I really appreciate is its practical and spacious interior. Computers, iPads, half-read books, thermos cups, and even a thin coat can all be neatly arranged in their respective places.
The Cool Student series lives up to its name. It is truly "cool" and very composed when used. 

Whether it's traveling around the campus or exploring the city, with its company, it feels like everything can be arranged in perfect order.
