Start with the two exterior pockets that appear to be a little bigger than an iPhone 8 Plus. Open them and it’s like reaching your hand into a can of Pringles, in that it feels like it’s a bottomless pit. In terms of travel needs, one pocket holds my iPhone, Airpods case and Breadcrumb. The other holds my Ekster wallet, keys and passport. Those pockets rest on a third exterior pocket that opens to reveal the “office supplies” section of the backpack—business card slot, two USB slots, two memory card slots, pen slots, a small pocket that I use for my Bluetooth mouse, a hook that I should use for my keys, a felt-lined pouch for a smaller tablet, and another zippered pocket that I houses my GoPro and selfie stick. And above that is a fourth exterior pocket that is slimmer and makes for a good spot for books and magazines, or yet another iPad or tablet.
