Help me (please) to identify this raincoat from the film "The Lobster"

Good evening ladies and gentlemen,

here it's D. from Italy, a 28-year-old N.H. who spends his week-ends in the countryside of South Italy.

I usually wear Barbour jackets for my divertissements.

Some weeks ago, I went to the cinema and watched (twice!) the film by Y. Lanthimos "The Lobster" (highly recommended). In this film, some people live into the woods, wearing some roomy, green-olive raincoats.

Here two pictures from the film:





I fell in love...

I'd like to have more information about these coats. Do they really exist? Do you know something similar? Can I buy one? :-)

Any help would be appreciated.

Thank you for your time.
