The Targus Work & Play Fitness 15.6" is suitable for active athletes. The backpack has several storage compartments you can use to for storing your gym clothes and water bottles. The top has a hook from which you can easily hang the backpack. Handy when you want to quickly take a shower, but don't want your things to get wet. Do you prefer to use the bag for your work? No problem, even a 15.6-inch laptop will fit in the designated laptop compartment. Thanks to the mesh material at the back, the chance of perspiring is small.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.
