Super capacity of this Backpack: The main compartment is large enough to accommodate an A4 binder with ease, and the laptop compartment will hold a 15" laptop/notebook. There are two zipped pockets, two open top pockets, and a velcro secured compartment also. The main compartment is closed by a canvas draw cord. There are 2 side pockets that will each hold a smart phone or a can of pop. I have tested it with an IPhone 6 4.7" model, and it fits like a glove. I would suggest keeping your phone in the main compartment if you are on a Tube train or busy street. There is an additional outer pocket that is secured by two straps with buckles. Once you have unbuckled the straps, you will find one zipped compartment. This is big enough to hold a very large smart phone, tablet or a wallet, even passports and documents. The shoulder straps are fully adjustable, so that you can wear the bag at the most comfortable height. Purchasing Notes: 1.
