✈ What do you want from a backpack? Charging your phone while traveling is a boon.
You also want a water-resistant backpack that will keep your computer (up to 17-inch size) safe from dampness.
Also necessary is a place for your keys and headphone, book, magazine and a few clothes that won't get damp if it rains. You want zips that won't break.
