Found this link to a Snug-it Pro Skin protective cover. Also, I believe "Camera Armor" has not made a cover for the D800 yet. I use a Camera Armor cover on my D80. It weighs around 1 lbs. Not sure if Snug-it is good or not, but I'm sure it's fine. Good luck!
It does show it back-ordered though on B&H.
