Whoever designed this bag was a genius.

There's a lot of back padding and shoulder straps are decently padded as well.

There's a pocket inside that can fit A4 folders and there's a velcro pocket just on the back so you could easily store something on your back that you don't want others to see/you want to protect.

A fair warning, I have used this backpack multiple times and I have gotten dirt from seats. You can safely throw this in the washer on a gentle cycle by itself and then air dry. This got rid of 90% of the dirt scuffs.
