on first inspection, I miss a base-plate, magnetic compass to be able to work with the map. Also because I wouldn't like to rely exclusively on electronics for something so sensible, not even for a short trip.
I'd also miss clean sleeping clothes; at a minimum, socks and pants. I wouldn't want to expose the bag's shell to skin, not even clean skin, and the hiking socks and pants are bound to be too dirty for the task.
Someone else already mentioned but I stress: some kind of towel is very important. I use a kitchen wipe at less than an ounce. It's much more than a convenience item, with the particularly important mission of wiping shelter inner walls when condensation happens. In general, to wipe any excess wetness to speed up the drying for things you want to keep as dry as possible.
Finally, I'd miss some packing stuff: little packing for little items like sunglasses, tarp, stakes, small essentials, maps or food items. Some of these may be not carried at all, some might be not counted because their weight is small... if the list is focused on functionality, that's fine but if precise weight measures are the goal, they do add up enough to make the list.
