I'm obsessed with this backpack. I bought it on a whim because I liked the clean look and the small size, two things that were important to me for a planned trip. When I say this is one of my favorite purchases EVER, I absolutely mean it.
It was amazingly light, surprisingly held a LOT more than expected, and looked great. Add onto that the fact that it stayed nice and tight to my body, so it made navigating narrow aisles a breeze (absolutely impossible with most backpacks). The only issue I ran into was that because the backpack is so thin I sometimes could feel my items (small boxed gifts) poking my back if they weren't positioned correctly. Adjusting items fixed the problem though, and if I had my laptop, or even just a folder in the pocket, it was a non-issue.
I think one of the best aspects of this backpack is, because it's so thin and small, it's able to fold up and take up almost no room/weight in another backpack/suitcase when not needed. That's assuming it ever left my back; I wore it exclusively EVERYWHERE for a 2-week trip (and now every weekend trip I take) because it's perfect.
