I am sorry for my confusion but I like your hat! Where did you get it?

Walter gets his hats from many different sources. One like the one above is being modelled amongst a troup of baboons that have stolen it from him.

It looks like a panama hat to me and if it's not a panama, it's very similar to a panama.

Take a look at the link below and I think you'll find similar hats in the hunting store at the bottom of the page: http://www.shakariconnection.com/safari-hats.html
