I packed mine up yesterday as realistically as possible. All of my camping gear, clothing etc is ultralight/compact. If optics are included, getting a week out of this thing is about impossible, especially with later season cold weather clothing. No matter how many pouches you put all over it, the main bag, where your food HAS to go is only so big. Unless you eat next to nothing, that is going to be your main limitation. I guess some guys like to sandwich a lot of crap in the meat shelf, I just don't. Incredibly well made, brilliant design, just still a 4400 ci pack. If you accept what it is, you will likely love this bag.
