I have reported on products from ECBC before, like the cool rolling luggage that is also a power supply, coming this summer.
Fortunately, you can get the Hercules Laptop Backpack K7102 right now. This backpack is “outdoor industry tested” 1000d Kodra material, with a water-repellent coating. It is good for 17-inch laptops, and it has a TSA-compliant compartment. This means that you can just lay on the TSA scanner with it zipped open and it will run through the scanner very fast. None of that putting the laptop on one of those gray tray things.
In addition to the efficient TSA problem-solver, it is padded to keep a laptop and tablet safe in travel, and the backpack is full of pockets. The front pocket itself opens to more and more pockets, and if you are willing to organize, you will never lose anything in this particular pack. The two side pockets open up to reveal some water or soda bottle holders.
You should be able to get the Hercules Laptop Backpack K7102 in Black, Blue, or Green for an MSRP of $139.99 here on the ECBC site.
