Help me find John Hammonds hat!

Hi, I recently rewatched the original Jurassic Park and have had John Hammond's hat on my mind for weeks now.

I really liked it, and it just so happens that I am getting out on my summer vacation in a few weeks here in Europe, and I know I'll spend several days out in the sun, so this is as good a time as any to get myself a new hat.

I did read a few threads on the RPF, but they went into too much details for me, I don't need an exact match for the hat from the film, but something close to it.

It should also be available in Europe from a reputable reseller so I can take delivery before my vacation.

I currently plan on pairing it with bright, loose fitting linnen trousers and a loose button down shirt, please feel free yo give me some more advice there, I am sadly overweight if that is relevant.

I'll add some photos of the character for your reference:
