The Avant Briefcase fits Passport, business documents, file folders, up to 15'' laptops, smartphones, chargers, cables, and other necessities. And, it is lightweight, durable, protective, and thoughtfully organized. Via Interlink, the Avant briefcase connects seamlessly and securely with the Avant carry-on for business trips. It can, however, be used separately. Its shoulder strap is just the right length to be functionally comfortable, and aesthetically attractive when used without the luggage.
