Who wears this hat in Indiana Jones, and when?

I saw a sale on the Indiana Jones website and was looking around when i came across this hat: a href="http://shop.starwars.com/catalog/product.xml?topcatID=408080;product_id=1219282" rel="nofollow"http://shop.starwars.com/catalog/product…/a I don't recall seeing the hat in the movies, and was wondering who the wearer is. As of now I'm just uming that Indy might wear it at some point in the movies, but I can't seem to find a scene where he does, but I'm not at all certain about this. Does anyone know who wears this hat?
