There are only 5 of these Official Avatar backpacks (replicas of the ones actually used in the film) in New Zealand.

Won this Item from TVNZ in conjunction with 20th Century Fox, but have only recently bought a new pack, and don't want to see memorabilia go to waste at the back of my wardrobe. So my loss your gain.

Backpack is around the size of a tramping pack, 800mm high 380mm wide 180mm depth. came with a waterbladder also in the side pocket. Compartment for a sleeping bag, money pouch, cell phone holders. detachable front part for possible lunch part. Waist strap and Ice-Pick holders. Am just listing observations of the pack, as I'm sure you wouldn't be using this in another planet with all the crazy things it was meant for.

Green, Grey, Orange & Yellow in Colour with black writing: AVTR Program ST-630, BioSeal -Protective barrier systems.

Welcome to come have a look before purchasing, even if you wanted to simply use this as a tramping pack.
