The Fjällräven Rucksack 21 Small is a stylish handy backpack made of strong and lightweight G-1000 material. This is suitable for treatment with Greenland Wax. You iron this wax in the fabric at a low temperature so that it is even better water-repellent. The Rucksack has a large main compartment where you can store a 13 inch laptop and other things. Put on the cord, flap over it and you are ready to go. You can store your small items in the many side and inner compartments.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.
