Forget the long coat.
Scottevest--started wearing their vests, and zippered sleeve convertible coats 6 years ago. Would never travel without one again. Carry a change of ultra light nylon shirt, ultralight nylon convertible pants, ultra light underwear, ultralight nylon rain hoody and micro dop kit fitted in the various pockets, so nothing shows and I still have pockets for my phone, passport and a paperback. I am good for 2-3 days on the road with no bag. If I am traveling a few weeks, I add three sets of same clothes in different colors rolled into a tight tube, a pair of shoes and a second micro dop kit and an iPad in a small Rick Steves or Eagle Creek ultralight roll aboard/backpack, box it and Fed Ex or mail it to a hotel I will be staying at overseas. I don't carry luggage through airports and security and on planes and customs anymore unless I have to. No need. No point. Scottevest and ultra light petro fabrics make it a snap. If you are an anal-paranoid, keep a backup pack boxed at a friend's back home with a filled out fed ex bill and if your first boxed pack gets lost or wrecked in shipping, email the friend to overnight or 3 day another. Or just go shopping locally. Ship the bag back home end of trip. Hands free travel!!!!
