“I gather that Tom Bihn designed this case to address the more restrictive carry on luggage rules that we have in Europe. So it is a quite a bit smaller (33 l.) than the Aeronaut (45l.) I reviewed previously. Fully loaded like it appears in the picture it fits perfectly into the luggage size testers at check-in desks. Being about 3″ shorter than the aeronaut it was a lot easier to fit into overhead baggage compartments, especially those on small commuter jets.
Another aspect of the Tri-Star is that it actually looks like a large pilot’s briefcase, and so does not appear out of place if you take the whole thing to a business meeting.”
