This bag exceeded my expectations. Here is a summary of what it has: a main compartment mostly for clothes and large items, one compartment for your shoes (with a ventilation hole), an adjustable strap that is comfortable to carry on your shoulders, one isolated side compartment ideal for wet clothes (or flip flops), two side compartments on the other side that are perfect slots to carry your cellphone, and the other one for wallets, keys and small items, and a few web compartments (with holes for ventilation) that are outside and inside the main compartment), and a computed compartment that I haven't used.Here is what exceeded my expectations: 1) it fits everything that I needed and more; 2) it's sturdy and keeps its form); 3) it has a couple of straps (as a casual daypack) that can remain hidden and that I even forgot it had in the first place;
