An amazingly comfortable laptop backpack, the Alienware Orion backpack will easily handle your 17" laptop. As heavy as the Alienwares are, you will not notice their weight with this backpack. The backpack is TSA-friendly, so you just unzip the laptop compartment, fully open it, and pass it through the X-ray machine without removing the laptop!
