I travel what you might call "incessantly", and I've been hunting for a travel pack that can keep up with me for ages. I'm also pretty tall (5'11"), and every other pack I've tried on has sat a little weird on me. The fact that this is super adjustable makes a huge difference. It's already been on a 3 week trip all over Europe, and it's coming on a 3.5-month lap of the globe here soon. The fact that it unzips all the way makes a huge difference, and the fact that the straps can be zipped away is fantastic if (god forbid) you're forced to check your bag. I highly recommend this one.
