Since I was an EFL peddler my trips were usually been years long affairs.
But I really HATE flying so I stuck with one suitcase with a week's worth of clothing, and my camera bag. Anything else I couldn't get get locally I had sent later. Winter clothes for example. But as the world globalized and internet shopping became the norm, even that wasn't necessary.
Short trips, like a weekend in Tokyo? That was a travel backpack with locks on the zippers.
Sadly my adventuring days are behind me and my only trips now are to the grocery store.
