The Aeronaut bag
by Tom Bihn, is a convertible carry-on travel bag that can comfortably
be carried over the shoulder duffel-style, or as a backpack if you
prefer. The bag is available in two sizes, the original Aeronaut 45 ($280), and it?s little brother, the Aeronaut 30
($270), and, as the name implies, 30″ or 45″ reflect their approximate
volumes in liters. Both bags interiors can be customized to suit your
needs, and both can carry a surprising amount of stuff, they feature
three significant compartments with panels that can be unzipped to create one large
compartment if you need more space. watch the video
