The Targus Gaming Backpack 17 inches is designed for gaming enthusiasts, with a laptop compartment that can store a laptop of up to 17.3 inches. It also sports a separate compartment for your keyboard, mouse, HDD, headphones, and glasses. Store your other items in the accessory compartment. At the side of the bag, there's a special compartment for a drinking bottle. Going to a game event on a drizzly Sunday? The backpack is splash proof and a rain cover is included as well. Gaming abroad? The backpack has a trolley sleeve, so you can easily attach the Targus to your suitcase. The padded shoulder straps and the chest strap ensure that the bag feels comfortably on your back.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.
