The Bolt Briefcase from Waterfield has a more traditional business case look, so it’s not quite as casual looking as a messenger bag can be. It will look equally at home in casual weekend use and in more formal business environments. It’s available in two sizes: small to fit up to a 13″ MacBook and large to fit up to a 17″ laptop. Both bags have padded laptop compartments inside, plus they have a variety of interior and exterior pockets to organize your smaller devices, cables, and chargers. There’s still room inside the bag for books or papers or even, according to the product’s video, gym clothes and shoes in the large bag. Both sizes are available in black ballistic nylon (slightly more formal looking) or waxed canvas base with naturally-tanned black, chocolate, or grizzly leather accents. The Bolt comes with a removable strap with a leather pad, splash-proof zippers, and invisible magnets to secure the front pockets.
