I'm picky when it comes to bags, and have purchased more than my fair share. I've bought camera bags, work bags, commuter bags, hiking day packs etc. Rather than something use specific I was looking for a travel pack that could do it all. Something very versatile, that I could use for international trips as well as my daily commute. I wanted something tough, sleek and that could carry a fair amount comfortably (and not knock people over when it was full). I also didn't want a garish color with a million straps. So far this pack is checking all the boxes. I've been using this for several weeks now for commuting to work, I love the laptop sleeve that is accessible from the top or side. I also took this bag on a trip tp Spain and it was awesome! I was able to fit 8 days worth of light packing plus my DSLR camera, and ipad pro with no problem (i'm a big guy, so a pair of shoes and a few pants/shorts takes up a lot of room). I used it as a carryon and had no problem fitting it into overhead bins, even on smaller planes it fit fine. After arrival I unpacked everything and used it as a day pack with just my camera and a few necessities, and it didn't feel cumbersome.
Overall the biggest selling point was the style. The black bag with a subtle black logo is sexy, and is what finalized my decision. Here's a pic of it in action, my wife using it in Spain.
