The Fjällräven Foldsack no. 1 is a sturdy and sturdy backpack for daily use to work or study. The flap on the top gives access to the main compartment. In the main compartment there is room for a 15 inch laptop, your lunch pack and a stack of A4 documents. You can put your smaller items in the zipper pocket at the front, under the flap. That way you know for sure that the items won't fall out quickly. The Foldsack is made of durable and sturdy material that can withstand the weight of your things.Note: the size of your laptop, such as 15 inch or 17.3 inch, 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 know for sure that your laptop will fit.
