By far the best backpack I have ever owned. There were a few cons, but I don't mind sharing them as other backpacks have so many more flaws.
1) Waist strap is cheap and hangs down when not in use. I took mine off, easy to do since it's an optional feature.
2) Padding had an area that wasn't consistent. It's on a spot that doesn't touch my back though, and it's such a small area. (like 1"x 1")
3) There's a tag on the inside of the backpack. A "Made in China" tag. Can't get it completely out without damaging the bag. I cut it close enough so it's unnoticeable though.
4) "Snug Fit Adapters" are confusing. I can't really explain what they look like, but it's pretty much a piece of foam surrounded by a plasticy fabric with Velcro. Still not sure what to do with them. If you have a 13" you may want to try and install them, but a 15" or 17" won't use them.
5) ^ The spacing can be tight if you use a sleeve. I have a 15" MBP and a Tom Bihn Cache Sleeve that I use. It's a tight fit for the backpack, but it works. Not sure how a 17" sleeve would work out. but a 13" with a sleeve should be perfect.
Now that's everything that's wrong with the bag. I'll list a few good things now:
1) Padding. The most comfortable backpack that I ever wore. This is coming from someone who spent High School wearing a Swiss Backpack with quadruple padding.
2) Light. This backpack near ways anything. I mentioned my Swiss Backpack in #1, this backpack ways less than that
with the laptop in it.
3) Space. It may look small, but this backpack has some serious storage space. The zippers zip all the way down too so you can fit everything you need to inside it. It also has a few compartments on the inside of the pack and as well as on the outside (front and back).
4) Zippers. Heavy duty zippers. Nothing cheap and flimsy. Also the backpack has a space for the zippers to fit under when you aren't using them, this protects them from the weather and other wear.
5) Looks. I love the style of this backpack, it's simple, sleek, and functional all at once.
6) Handle. Great handle on the backpack. It's actually heavy duty Pleather. Nothing cheap and flimsy.
