The Thule Crossover 15 inches Black is a handy backpack to take to work or to school. The backpack has a 15-inch laptop compartment and a tablet compartment so you can transport your devices safely. With a capacity of 32 liters, the backpack has space for A4 documents and your packed lunch. You can take accessories such as your phone or pens with you in the special compartments, so you will never have to search for your belongings for a long time. The back panel has ventilation systems, so your back stays cool.Note: the size of your laptop, such as 15 inches or 17.3 inches, is the size of the screen, not of your entire laptop. If the edge around your screen is wide, choose a laptop compartment in a larger size to be sure. This way, you can be sure that your laptop will fit.
