So what I found with this bag is that it is easy to organize all of your stuff while remaining very convenient to get to. I was trying to decide between this bag and the Especial Tres and I like this bag a little bit more because everything is more convenient to access. There are only a few things I would do to make this bag better. I would add another stretch pocket like on the Tres to hold a u-lock secure so that there is a place for both a water bottle and a lock. That being said I put my lock in one of the front pockets. The other things is I would make the bag a little bigger like the Tres (but maybe not THAT big). That last thing it lacks (and this is a big one) is the laptop pocket is not waterproof (or at least I haven't been corrected about that yet). That being said; this bag is fantastic. It is big enough for me to carry a couple changes of clothes (one for work and some gym clothes), a couple textbooks, a big lunchbox, and my laptop with the ability access all of it easily.
