I have to say in the couple of months that I've owned this pack, I really like it a lot, I bought this for work use, to carry a 14" HP laptop, which it does securely in the padded section.
Overall the pack is very comfortable for hoofing it across the long parking lots at work to get to my building, including the shoulder straps and back panel, which is nicely padded and stiff to support good size weight loads, with a plastic panel to help distribute weight. The padding on the back panel is vented to dissipate heat, but doesn't absorb sweat easily if one is prone to that.
It has lots of pockets to organize one's cables and other gear, a nice size larger middle section for stuff like file folders and notebooks, along with another decent-sized smaller one to hold a bit more, including a tablet if one is inclined to do so.
The organizer panel is good too, with ample pen loops for those of us that still use and carry them, which is something that I found most of the packs I looked at had too few or none of.
The two bottom pockets on the outside are handy for an umbrella and water bottle or coffee mug, and the two top side pockets great for cables. I love the reinforced sunglasses pocket, which is great for protecting expensive glasses, though it is a bit large - large enough to hold goggles I should think.
The one additional outer pocket at the top is great for little quick access items you need like lip balm, a Listerine spray and such, with two elasticized pockets inside the flap. What could make this better would be elastic edges on the flap itself, so you can store things in the open portion and not have them fall out when the flap is zipped completely open.
The pack is capacious without being sloppy or bulky, and I anticipate it would slip under a seat on an airplane without issue, which will be handy when I start traveling for business. I find that I could easily stuff a ton more than I do and it still rides well when walking vigorously, without sloshing about.
It's a nice blend of classy looking, with a sporty edge, but still works for business use, making it professional looking, but distinctive compare to its more boring counterparts in the market. Materials seem top-notch, with ballistic nylon throughout, and I expect will be durable for years of use.
The negatives of this pack are largely very small. The lack of a key strap/clip in the organizer panel is a notable, significant oversight in my view, and exceedingly annoying, but not enough to not like this pack a lot - I'll probably sew my own in, given my proclivity for occasionally losing my keys.
I'd like to see the straps be a little longer, they are only just long enough for comfort for me as a 6'3" man. Taller folks than I will find the straps too short, with the padding stopping too short in the front of one's chest and below one's armpits.
The other oversight is the media/phone pocket on the left strap, which is effectively functionally useless for any of today's smartphones, especially plus-sized ones, because it's too small to get one in. The only other thing I might like to see added to the pack is perhaps a couple of daisy-chain loops on the outside to clip stuff to on the outside, but again, this is a small negative.
