Bag is well done and so thought out - material is fantastic and there is PLENTY of space and room for anything and everything. Instead of repeating the specifics of the bag, let me provide some cons that I wish I knew prior: 1) It's quite large - the measurements provided don't do seem to it justice. And it's heavy and firm. Packed up it's an absolute beast. When grabbing to pick it up, this is one of the things I repeatedly noticed 2) One of the inner walls seems to have a firm piece of cardboard (or plastic?) sewn into it to keep its shape. Seemed unnecessary to me and maybe would have been fine without this insert which makes the bag quite stiff/adds bulk. 3) the double zip on the top is an interesting feature that allows full exposure but could get a little annoying to some. 4) maybe not a real con but the abundance of organization availability and pockets almost borders on excessive - if that's your thing then you will be in love but it's definitely not for the minimalist inclined. 5) While it's designed in Idaho, it is not made in the USA - which I found particularly surprising given how the company markets and brands itself. Just saying. I also own the Apprentice backpack and love it. This is brief is indeed another winner, I can see the role it fills in the Eberlestock line up, but it may be just a bit too much and too big/bulky for my personal daily office carry.
