The main idea is to distribute weight more evenly from front and back.
And detachable front bag so you can keep your heavier main bag in the locker while front bag is carried in between classes.
There would be no strap.
The outer skin is made with hard shell
All the contact points would have ample padding (esp in shoulder) for comfort.
The front portion would be right size for laptops to evenly distribute weight from back and front and also for easy access.
