I got the 45L (compresses to 30L) Peak Design backpack for carry-on-only travel. https://www.peakdesign.com/products/travel-backpack?variant=11530908172332 https://www.peakdesign.com/products/travel-backpack?variant=... $300 is a doozy, but the quality is noticeable, and it was one of the few backpacks I saw that unzips into one big compartment which is what I want when I'm packing a bunch of clothes. Too many backpacks seems to maximize compartment count where I don't really understand the utility and it limits what I can stuff in there. My girlfriend's Osprey pack has the same volume but is split into four compartments that can barely fit a pair of jeans. And it also looks modest but cool. Most packs in the space make you look like you're about to go camping, there's enough of that.
