The long plague doctor coat was another great way to protect oneself from catching the disease. No one wants that bad air getting on their skin. And the pouch on the side contains all sorts of medicinal items that a plague doctor might need at short notice. Your minifigures will thank you for the extra protection while treating patients. And they'll be happy for such a stylish medieval outfit!
This coat is also perfect for minifigure monks who desire a new well fit robe.
