Familiarity: I've put it through the wringer
My husband and I both got these for our 3 week trip to Europe. We wanted something that we could carry around while traveling, so we wouldn't be loaded down with bags. After a ton of research, I found this pack to be the best option.
It is the maximum liter size that is allowed on airplanes as carry-ons which is great because we didn't want any additional fees from checking bags. They fit in the overhead compartment easily and don't have a ton of external pockets so things weren't getting caught or snagging. While the pack protrudes off your back kinda far, it is a fairly sleek design.
I love how the zipper opens up so wide so it is like a duffel, rather than a standard backpack or top loader. Really easy for me to see everything inside and organize it how I wanted to. There was plenty of room for me to store 3 weeks worth of clothing as well as toiletries, a couple extra pairs of shoes, electronics, and all my documentation. Packing cubes were a huge help for organization.
Having the straps stow away was a lifesaver in Europe. One of the airlines we flew only allowed for smaller carry-ons so they checked our bags at the gate. (European airlines have different carry-on sizes than American) We hurried and stuffed our straps inside the packs so they wouldn't get caught on anything during transfers. There were not torn or broken straps to worry about when we got them back. Since they're able to be stowed away, the hip straps aren't too burly or supportive which means they aren't the most comfortable, but it was worth it and we carried them lots of miles while traveling.
We still use these all the time when we're going on quick trips to relatives or even camping. It's nice to not have to worry about a big suitcase. It also helps keep us from overpacking!
