Summary: I'm really happy with this purchase, this bag is everything I hoped it would be. The upper pocket (for jackets, food, etc.) is even bigger than I thought it would be, which is a big plus. The gear sections in the bottom provide ample room for my D40, a few lenses, my flash, chargers, extra batteries, and more. I'll be able to speak more to the practical functionality of the bag after I've used it on the other side of the world.
