STM Evolution Backpack

We've been using various STM bags for years now. They're superbly built, have tons of compartments and pockets, and just the right amount of tech style. STM's latest, the Evolution backpack ($100-$110), is no different. We've had one for about a week now, and it has already put all of our other backpacks to shame. The Evolution has a concealed waterproof laptop section, a built-in stow-away raincover, tons of pockets and organizers, a removable iPod pouch, and super comfortable straps. It comes in two sizes — small to fit laptops up to 13.3 inches and medium to fit laptops up to 15 inches.
