Right, the link didn't work for me as well.
I only saw two black coats in the mens section, and the main difference I saw was 1 had a sort of cuff thing and the other didn't.
Was it by any chance one of these.

I found it on the Swedish section of the H&M website.
Maybe I should introduce myself, too...
