I'm considering an aeronaut45 and I've never tried using soft luggage like this before. Assuming I get everything packed inside, I'm wondering how people keep it relatively clean.
For example, I often take taxis in developing countries and have to store luggage in their sometimes oily trunks. I also wonder where I should put the bag when I have to use the airport restrooms.
Basically, since I plan to carry it on my back most of the time, all that gunk is going to get transferred to the clothes on my back.
What do you all do to keep yourselves relatively clean when using the aeronaut?
