Hacker, convertible vertical laptop bag. Carry it with a shoulder strap or as a backpack.
The Hacker bag takes the Blogger bag to the next level, adding a waterproof liner and bottom, a molded back panel, enclosed padded, corduroy-lined laptop compartment and it also coverts into a backpack with straps that are normally hidden in the back, which are great for going on long hauls. In general, vertical laptop bags take up less space, which is important when you’re at crowed art or tech events.
It holds a laptop vertically, so it doesn’t bend against the curve of your hip, and it doesn’t bump into pedestrians when you hustle through crowded sidewalks. The corduroy lined laptop sleeve is built-in, has a velcro fastening strap, and its bottom is positioned slightly off the bottom of the actual bag, to protect your computer from shock.
