Aeronaut 45

Our legendary maximum size carry-on travel bag. Carry it as a backpack, shoulder bag, or duffel. Travel with the Aeronaut isn't like travel with wheeled luggage: you won't ever hesitate to make your way through the crowd, down a cobblestone alley, across the grass, or up the trail. With the load on your back, you can navigate through not just airports, train stations, and bus depots, but through airplanes, trains, and buses. Hard to categorize, the Aeronaut is at once soft luggage, a duffel bag, and a backpack. It takes the best of all those bags and combines them into what many people have found to be their most versatile travel bag yet.
