Escort/Travel companion:

The suitcase is the life buoy in the surf of the modern travel community. Their needs on a large scale are summarized there in a space-saving and usually rectangular way: Storage, charging station, means of transport, mobile office, sleeping and washing facilities. Is the suitcase just an optimized piece of luggage or can it also serve the desires of circumnavigators, adventurers, deep-sea divers or cosmonauts?
