The Deuter XV 3 SL 15 inch is a backpack specially designed for women. The backpack is suitable for daily use as well as for sporting activities. You take your laptop safely to school or work in the 15.6-inch padded laptop compartment. Are you going for a bike ride? No point. The bag is light weight so you hardly realize you are wearing it. Because women on average have a shorter back than men, this backpack is shorter than other backpacks. Thanks to the contoured shoulder straps and hip belt, the bag stays in place. The stretchable compartment on the front has room for, for example, a bicycle helmet or extra sweater. You put your drinking bottle and energy bar in the elastic side pockets of the bag.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 border around your screen is wide, choose a laptop compartment in a larger size to be sure. That way you know for sure that your laptop will fit.
