which backpack actually works for travel and class?

I’ve been losing sleep over picking the right backpack for my Europe trip—seriously, I think I’ve watched every YouTube review out there. I need something that can handle my laptop for classes, but also won’t make me look like I’m hiking the Alps when I’m just hopping on a budget airline for a weekend getaway. The worst part? Every time I think I’ve made up my mind, I picture myself trying to stuff it under a RyanAir seat and panic all over again. Right now, I’m torn between the Herschel Classic XL (30L), CabinZero Tech, and the Calpak Luka. I keep imagining myself in a tiny European classroom, trying to look put-together, but then fast forward to me sprinting through an airport, backpack bouncing, and I wonder if any of these bags can actually do both jobs. And don’t even get me started on packing cubes—are they really worth the hype, or just another thing to overthink? Has anyone actually managed to find a backpack that works for both class and travel, and doesn’t get you side-eyed by airline staff? I feel like I’m destined to pick the wrong one and regret it the whole trip. I’d love to hear what’s worked (or totally failed) for you, especially if you’ve survived RyanAir’s personal item drama. #travelproblems #backpackdilemma #studyabroad #Travel
