I've been doing all my travel for the last few years in a Cotopaxi backpack ("Allpa"); it's 35L, opens flat for easy packing/organization, has sufficient pockets for tidiness, and excellent external handles for managing it when it's NOT on your back. It's also carryon-legal for even international flights, which is handy. I got mine on deep discount for about half the going price now, but if something happened to mine I wouldn't hesitate to buy a replacement at full price. https://www.cotopaxi.com/products/allpa-35l-travel-pack?variant=39514009665597 https://www.cotopaxi.com/products/allpa-35l-travel-pack?vari...
