Super ultralite?

I'm no expert on ultra light gear. My base weight was hovering around 15 lbs on the PCT this summer.

Ditch the Nalgene, get a Gatorade bottle. You could lose many pounds by switching to a lightweight sil nylon internal frame pack.
Ditch the knife, rip cheese with your fingers. You don't really need cord to hang food (others may disagree), frogg toggs rain coat, etc.
