You can fit a notebook or tablet up to 10" large inside the backpack's main compartment, which has a separate padded pocket for these devices. The main compartment also has a handy double puller zipper for quicker opening/closing. The main pocket is extremely spacious; it opens up to fit items inside effortlessly, with plenty of space for all of your possessions. It makes a great work backpack. There are even small, discreet pockets on the back in the panelling and on one shoulder strap for your phone, cards, etc.
