pretty good. solid construction. water proof. i'm not a messenger, so i don't need the 5,000 little pockets on the front. ample space on the inside with some good pocket segmentation. I was hoping that it would align more diagonally across my back compared to sitting at the hip, but i supposed that's my fault for not looking into it more. the clip to secure the bag works, but sometimes you'll catch it on something and it will go loose pretty easily.

I love this guide, and it's proven very useful, but it's riddled with typos and some of the answers indicated to the questions are incorrect. Overall, I am satisfied with this book, and would recommend it to others. However, it is not the only guide I will be purchasing.
