Club Obi Wan

I just saw Indiana Jones and the Crystal Skull and was wondering if anyone knew what kind of backpack he had in the graveyard scene with Mutt?

there were some discussions about the backpack here:

And the original pic the discussion was based on: http://theraider.net/films/indy4/galler ... ij4_03.jpg

Awesome guys! Thanks!!
