The 40.64 cm (16 inch) Grid Advanced Backpack has a fully padded exterior, and separate padded laptop and lined tablet nooks on the interior. All of this padding adds up to military specifications protecting your laptop from a 4ft drop. The interior provides 32 liters of storage broken down into two main compartments and three external stash pockets. The main compartment houses the laptop and tablet nooks, with plenty of additional room for books, files or reference materials. The other compartment has several mesh pockets along with plenty of additional storage. There are two zippered stash pockets on the front and one hidden in the bottom pad on the back. The bottom panel is reinforced with extra padding and weather resistant material. The main compartment (with device nooks) also has a weather resistant zipper. Padded, adjustable shoulder straps and aerated, padded back ensure a comfortable fit once it's on your shoulders.
