Bought it for a trip to France! I didn't use it as a carry-on, because it's definitely a little bit too small (I definitely tried! I'm sure it's possible if you're not paranoid and extra like me) but it was the perfect daypack. I wanted something slim and sleek enough so I didn't look super dorky, especially when carrying it as a crossbody. Clips and zippers are super easy, straps held up great, though I will caution everyone that they're gonna be awkward convertible backpack straps, so it's always a struggle. But that's a given with bags like these. I got pretty good at switching around the configuration after two weeks.It fits a TON, surprisingly! I was able to cram an umbrella, 16oz Swell bottle, sunglasses, personal items, a snack, my journal, and still cram in some random souvenirs and stuff I picked up! Totally recommend this little gem. Super secure, sleek, and it's exactly what anyone could need. It really helped me not overpack for walking around cities all day- do you really need a 35L Jansport for that?I still use it frequently back and forth on my bike to work and whatnot. Definitely recommend!!! Especially for the price.
