Our Mountain Briefcase is the ultimate shape changing, go to work, bum around town, travel the world, do it all every day carry. We took the silhouette of a classic briefcase, kept all the good looks and buttoned up styling needed for any business meeting, and added enough functionality to throw it on your back and head outside as soon as business is done. We've engineered it for a 3-way carry system which allows for a traditional two handle briefcase style, as a backpack with stowable straps, or over the shoulder with a removable shoulder strap. The interior has a large main compartment, padded laptop sleeve with velcro closure, zippered storage pocket, pen slots, and open top notebook pocket. The exterior has a zippered notebook pocket and the base has two cinch straps that can hold a rain jacket or those blueprints to your solar powered geodesic dome.
