I keep the really important stuff in a travel wallet. It's about as high as a letter/A4 piece of paper is wide, it holds some money and passports, and I could throw my cell phone in it. The rest of the stuff can be tossed, but that's going with me. Keep an eye out for one - the long ones are not easy to find, and the company that made mine is out of business. Example: https://www.leatherology.com/products/zip-around-travel-wallet-black-onyx https://www.leatherology.com/products/zip-around-travel-wall... (no knowledge about the company or the product, just what I found with a quick search).
