The Case Logic Jaunt Backpack 15 inches is the answer to the question of how to most efficiently take your daily necessities along. A special place has been reserved for both your 15.6-inch laptop and tablet, so that they'll remain protected against scratches and bumps. There are sufficient compartments available to store all your other accessories and documents. A water bottle can be stored on the side of the Case Logic Jaunt, so you can quickly access it when you're on the go.Note: the size of your laptop, like 15-inch or 17.3-inch, is the screen size, not your whole laptop. If your laptop has wide bezels around the screen, it's better to choose a laptop compartment that's a size bigger. That way you'll know for sure that your laptop fits.
