I just got my brain bag and I'm pretty happy with it, especially when there are so many pockets and neat gadget like stuff (and I like gadgets :) ).
However, there are a few things I don't understand how to use on the bag, and I would like to utilize the bag to its fullest potential.
1) There's a strap in the middle between the two pockets in the front. Is this the umbrella strap? If so, how do you use it.
2) There's another strap right below that. What is this for and how do you use it?
3) There are clips on both sides of the bag. What are they designed to do?
4) I assume that the front mesh pocket is for a water bottle?
