Where's your raingear? You'd be pretty miserable if it starts raining and you don't have any
Of course, I hardly see any clothes at all there. Surely you want at least a backup pair of socks; wet socks are pretty miserable to hike in and encourage disease. Actually, two pair, since proper hiking footwear is a good pair of boots, a thick outer layer of socks, and a thin inner layer.
Don't see any cutlery in the list. A titanium spork is usually a good general purpose eating utensil.
What's your water storage? I'm a big fan of water bladders myself.
A few optionals if you don't mind the extra weight/space (since you're taking a hammock, I'm assuming it's not too critical):
* A lightweight collapsible chair; not having to sit on the ground all the time can be nice.
* A daypack. Especially useful if you have a dry camp and need to make trips for water.
Out of curiosity --seeing your mention of deet bug repellant: has anyone tried catnip oil-based repellants? I read a study from Iowa State last year in which they determined that the essential oil of catnip is a 10 times more powerful mosquito repellant than deet. I ordered a vial of the essential oil and plan to dilute it and give it a try, but if anyone has any experience, I'd like to hear about it.
