Cleanliness. Chic. Holds lots of books and my laptop. I particularly like the padding on the back and on the straps, which relieve the back and shoulders. I carry my laptop to work and class all day. I usually walk about 4 miles to work in the city and I've noticed that my crotch is less tight with this backpack. Does not sway, sits well on the shoulders; This is a must have for busy graduate students or commuters looking for a comfortable yet clean and modern backpack. I did not use a USB charger. It feels bulky and unnecessary, but luckily the cable can be discreetly hidden.
