I "did a year" in Greenland, compliments of the US Air Force. A friend that had preceeded me there, told me to make sure that when I got issued a parka to get the one with the stiff ugly fur, not the nice soft fur.

For the next year, I was able to knock the frost off my snorkle parka with a quick slap. Others with the soft fur had to pull the parka over their heads and thaw them out before they could open the frozen fur snorkle. Wolverine fur works MUCH better than anything else.
